This article will give detailed information about brass metal.
The article will give details on the following:
Brass refers to a variety of copper-zinc alloys known for their durability, strength, longevity, and corrosion resistance. The mechanical, corrosion, and thermal properties of brass can be adjusted by altering the copper-to-zinc ratio to suit different applications. Typically, brass contains between 60% to over 80% copper, with zinc making up less than 10% to more than 40% of the alloy.
Brass with a zinc content exceeding 30% is termed high brass. This alloy is more brittle, less malleable, and harder to shape. Increased zinc content also makes brass more prone to corrosion, as zinc reacts with air and water to form a zinc oxide layer.
Brass with a high copper content, typically above 85%, is known as red brass or gunmetal. This high copper percentage imparts excellent malleability, ductility, corrosion resistance, and ease of shaping and forming. Red brass is highly machinable, allowing for easy cutting, forming, and drilling. However, the high copper content also results in a higher cost for red brass.
Lead is added to brass as a stabilizer in copper and zinc alloys, enhancing its malleability and machinability. However, due to health risks associated with lead inhalation, the amount of lead permitted in brass is strictly regulated. Typically, lead content in brass should not exceed 2%, with some regions enforcing even stricter limits.
The Unified Numbering System for Metals and Alloys (UNS) assigns a unique identifier to each metal type, consisting of a letter followed by five digits. This number specifies the chemical composition of the metal or alloy rather than its mechanical properties. The first three digits of a UNS number are derived from other numbering systems.
For brass, the UNS designation starts with the letter "C" followed by five numbers. The categories are as follows: C20000 to C29999 for yellow brass, C30000 to C39999 for leaded brass, C40000 to C49999 for tin brass, and C87300 to C87900 for cast silicon brass. Red brass, which contains 85% copper, is designated as C23000.
The malleability of brass is influenced by its zinc content. When the zinc percentage exceeds 45%, the brass becomes difficult to work with. In brazing (soldering), a coarse variant known as white brass is used. While not economically significant, white brass serves as a base for die casting alloys.
Brasses with less than 40% zinc are pliable and suitable for cold working. Alpha brass, with a zinc content under 37%, is named for its specific crystal structure. Alpha-beta brass, also known as duplex or hot-working brass, has a zinc content between 37% and 45% and features both alpha and beta grain structures.
While copper and zinc are the primary components in brass, other elements like lead are added to improve physical and mechanical properties and enhance corrosion resistance. Naval brass, a type of alpha-beta brass, contains 59% copper, 40% zinc, 1% tin, and a small amount of lead. The tin in naval brass improves its resistance to seawater corrosion.
Different types of brass are distinguished by their crystal structure, which can be face-centered cubic (FCC) or body-centered cubic (BCC). Brass with a high copper content exhibits an FCC structure, similar to copper itself, with copper atoms at the corners and center of each face of the unit cell and zinc atoms occupying the spaces between them. Brass with a higher zinc content has a BCC structure.
Brass can exhibit various colors, including reddish-gold, silvery-white, or bright gold. An increase in zinc imparts a silvery appearance to the alloy, while a higher copper content gives it a rose-colored hue.
Brass is more malleable than both bronze and zinc.
Brass alloys are favored in metalworking for their toughness and corrosion resistance. The properties and characteristics of brass vary based on the copper-to-zinc ratio and the addition of other alloys. Elements such as tin, aluminum, iron, and lead enhance the deformability, machinability, and tensile strength of brass.
Alpha brass, while remaining a monophasic alloy, presents a distinct yellowish tint compared to red brass. Despite its susceptibility to degradation under certain environmental conditions and temperatures, its functionality remains unaffected. Alpha brass offers superior mechanical strength and ductility relative to other brass types, making it particularly well-suited for various forming applications.
Alpha brass, known as "cartridge brass," is used for ammunition cartridges, heat exchanger tubes, evaporators and automotive radiators, fire extinguishers, rivets, bolts, and screws. It is named for its homogeneous alpha crystal structure and its less than 37% zinc content.
Combining zinc with copper results in a solution that forms an alpha crystal structure with a uniform composition. Alpha brasses are noted for their softness, ductility, and malleability, which makes them ideal for cold working, welding, rolling, drawing, bending, and brazing. This type of brass is commonly known as 70/30 brass due to its composition of 70% copper and 30% zinc.
Alpha brass is known for its blend of durability and adaptability, making it suitable for cold drawing processes. Its higher zinc percentage enhances its resistance to corrosion. It is commonly utilized for manufacturing electrical socket springs and various fasteners such as wood screws. Alpha brass retains its shape well and is less susceptible to dezincification, a phenomenon where zinc gradually deteriorates over time.
Alpha-beta brasses, known as "duplex brasses" or "hot-working brasses", have an alpha-grain structure and a beta-grain structure with a zinc content between 37% and 45%. They are atomically comparable to pure zinc with the zinc content determining the alpha-phase to beta-phase brass ratio. Alloys, such as aluminum, silicon, or tin, can enhance the quality of beta-phase brass.
Alpha-beta brass, which is more common than alpha brass, offers greater toughness and strength but has reduced cold ductility. This type of brass is more cost-effective due to its higher zinc content but is also more susceptible to dezincification corrosion.
Although alpha-beta brasses are less malleable at room temperature compared to alpha brasses, they are much more workable at elevated temperatures. These brasses also exhibit resistance to cracking, even when lead is added to improve machinability. Typically, alpha-beta brass is processed through methods such as extrusion, stamping, or die casting.
An example of alpha-beta brass is Muntz metal, developed by George Frederick Muntz in 1830 as an alternative for wooden ship hulls. This alloy has a 60:40 ratio of copper to zinc and contains small amounts of lead, making it highly durable. While still used in shipbuilding, Muntz metal is now also utilized in the production of various fittings, pipes, and springs.
Beta brasses are known for their strength and toughness, making them ideal for casting applications. They are characterized by their bright appearance and less golden hue, attributed to their higher zinc and lower copper content. With a beta crystal structure, these brasses exhibit greater hardness and strength compared to alpha and alpha-beta brasses. Due to this structure, they can only be processed through hot working methods.
Beta brasses represent the third category of brass alloys and are the least commonly used. With a zinc content of 45%, they offer enhanced toughness and strength due to their beta crystal structure. Various forms of beta brass include machining brass, high tensile brass, naval brass, dezincification-resistant brass, cold working brass, and casting brass.
Incorporating lead into brass improves its machinability by serving as both a chip breaker and a lubricant. Since lead does not dissolve in brass, it remains as free particles along the grain boundaries. This addition not only enhances the strength of brass but also boosts its corrosion resistance. Lead content in brass can be as high as 3.5%, and the brass can be categorized as high, medium, or low leaded based on the amount of lead present.
There are two primary types of leaded brass: alpha (α) and alpha-beta (α+β). Alpha (α) leaded brass is typically cold-formed or hot-extruded due to its limited plasticity at elevated temperatures. In contrast, alpha-beta (α+β) leaded brass retains sufficient plasticity at high temperatures, making it suitable for forging processes.
Grades such as C34500 and C35300 represent high leaded brass, while C38000 is classified as low leaded brass. High leaded brass is commonly used for manufacturing pinions, gears, valve stems, flare fittings, and adapters. Low leaded architectural brass, on the other hand, is employed in the production of thresholds and frames for doors and windows.
Lead brass is available in forms such as pipes, bars, and tubes, and can be customized to meet specific application requirements. However, due to its lead content, it is considered hazardous and must be handled with caution.
As regulations on lead use in products tighten, brass manufacturers have turned to alternative alloys to replicate the properties previously achieved with lead. New alloys, such as those containing silicon and bismuth, offer similar machinability and excellent pressure tightness as leaded brass.
Even with the shift to lead-free brass, trace amounts of lead, up to 0.25%, are still allowed. This amount represents a significant reduction, being 32 times less than the levels used in the past.
Grade C87600 is an example of lead-free silicon brass that maintains excellent machinability and pressure tightness while resembling leaded brass in appearance. Lead-free brass valves and connectors are marked with an “LF” designation on their bodies and a plastic tag. Current regulations prohibit the installation of leaded brass in homes unless it contains 0.25% or less lead.
Lead-free brass is primarily composed of zinc and copper, with the ratio adjusted to meet specific application requirements. High copper content is preferred for machining applications, whereas high zinc content is beneficial for strength. Additional elements such as aluminum and manganese may be incorporated to achieve desired properties.
Adding tin to brass enhances its heat resistance and makes it more resistant to corrosion from seawater, earning it the name "naval brass." Tin integrates well into copper-based alloys, reinforcing their structure.
As the tin content increases, the alloy can become brittle (CuZnSn complex) and less suitable for plastic deformation. The tin content in tin brass ranges from 0.5% to 1.5%, with common types including HSn70-1, HSn62-1, and HSn60-1.
HSn70-1 is known for its excellent plasticity, allowing it to be formed by both hot and cold pressing, making it suitable for pipe manufacturing. In contrast, HSn62-1 and HSn60-1 exhibit α and (α+β) two-phase structures with a minimal α phase, resulting in reduced plasticity at room temperature and requiring high temperatures for deformation.
Tin brass, or naval brass, is primarily used in marine applications such as boat and ship construction, with a typical composition of 59% copper, 40% zinc, 1% tin, and minor amounts of lead. Besides shipbuilding, it is also utilized in components exposed to moisture and humidity.
Architectural bronze is considered a type of brass due to its zinc content, distinguishing it from traditional bronze, which is primarily composed of tin and copper. This alloy typically contains 55% to 59% copper, 2.5% to 3.5% lead, and 0.35% iron, with small amounts of zinc. Its combination of affordability, durability, and corrosion resistance makes it well-suited for industrial uses.
Architectural bronze can be shaped using various techniques, including hot forming, bending, brazing, soldering, butt welding, and machining. The material is hot-formed at temperatures ranging from 1150°F to 1350°F (621°C to 732°C) and is annealed at temperatures between 800°F and 1100°F (426°C to 593°C).
Manganese brass is an alloy primarily consisting of copper and zinc, with a 3% manganese content. It is capable of withstanding substantial loads and high-speed applications. Known under UNS grade C86300, it is commonly called manganese bronze. The alloy's exceptional strength and durability make it well-suited for heavy load bearings, hydraulic cylinder components, and large valve stems.
The key features of manganese brass include its remarkable strength and resistance to corrosion. The addition of manganese, ranging from 1% to 4%, significantly enhances the properties of brass due to manganese’s high solubility in the alloy. Manganese brass typically exhibits both alpha and alpha-beta crystal structures and can be processed using either hot or cold working methods.
With a Rockwell hardness rating of B95, manganese brass is available in bar and rod forms. Both forms are highly resistant to wear and maintain their strength over time thanks to their superior fatigue resistance. It is particularly valued for applications requiring corrosion resistance, anti-seizing characteristics, and high strength.
Manganese brass is employed in various demanding applications, including those involving heavy loads and requiring high shaft hardness in non-abrasive environments. Its use is prevalent in the aerospace industry for components such as landing gear parts, bearings, bushings, gears, and screw nuts, where it provides robust performance in challenging conditions.
Iron brass features an alpha-beta crystal structure and contains less than 1.5% iron. This alloy has a silvery appearance and combines toughness and strength with good plasticity at elevated temperatures. Its composition typically includes 50% to 61% copper, 17% to 19% zinc, 21% to 30% nickel, and up to 1.5% iron.
During production, iron is introduced into a molten blend of copper, zinc, and nickel. Iron brass exhibits an alpha-beta (α+β) crystal structure and tends to become less ductile in colder environments.
Iron brass is represented by alloys such as Alloy 280 (Muntz Metal) and Alloy C360 (Free Machining Brass). Both alloys consist of 60% copper and 35% to 40% zinc. Muntz Metal, with its minimal iron content, is commonly used for ship hulls. Free Machining Brass, which contains lead along with iron, is known for its ease of machining.
The addition of iron enhances the hardness of these alloys. For Muntz Metal and Free Machining Brass, iron contributes to their increased hardness and forgiability, which is not achievable with pure copper or many of its alloys.
Nickel brass exhibits a gold-like color that varies with the nickel content and remains resistant to discoloration and tarnishing over time. The incorporation of nickel into brass raises its recrystallization temperature and results in a finer grain structure. Nickel significantly enhances the alloy's resistance to corrosion from both air and seawater.
Nickel brass is primarily made from copper and zinc, similar to other brass types. However, instead of the typical 60% copper and 40% zinc ratio, nickel brass usually consists of 60% copper, 20% zinc, and 20% nickel. The nickel content affects the color of the alloy, which is why nickel brass is also known as nickel silver or German silver due to its silvery appearance.
While nickel brass shares general corrosion resistance properties with other brass alloys, its higher nickel content imparts additional benefits such as superior tarnish resistance and enhanced protection against stress corrosion cracking.
Nickel brass is commonly used in the production of coins due to its difficulty to counterfeit and its distinctive electromagnetic signature, which is useful for coin validation systems. It is also widely used in the manufacture of musical instruments, valued for its durability and tonal qualities.
Single-phase brass is created when zinc is dissolved in copper at levels below 35% zinc. This type of brass is typically deformed through cold rolling and is known for its high ductility and flexibility, thanks to its low zinc content.
Double-phase brass, which contains both alpha (α) and beta (β) phases, has a zinc content ranging from 36% to 46%. The higher zinc content in the beta phase reduces plasticity but increases tensile strength. This type of brass is often processed using high-pressure techniques.
In double-phase brass, the alpha phase consists of a copper-zinc solution, whereas the beta phase has a higher zinc percentage. This combination imparts double-phase brass with notable corrosion resistance, strength, and excellent machinability. The tensile strength and overall performance of double-phase brass are significantly enhanced by increasing the zinc content.
Bolts, nuts, washers, springs, and structural components for electrical equipment use double-phase brass. Single-phase brass is cold form due to its flexibility while double-phase brass is hot formed because of its high zinc content.
Brass is well-suited for decorative uses due to its attractive appearance, while its strength, durability, and resistance to corrosion make it valuable for mechanical applications. Its low friction properties also make brass an excellent choice for manufacturing fasteners, connectors, tools, and ammunition components.
