Brass

Some of the common types of brass available include:

• Red brass
• Yellow brass
• 330 brass
• 360 brass
• 464 brass

Other properties of brass include the following

• Muted yellow/gold color (depending on the amount of zinc)
• High corrosion resistance (especially if it contains an above-average amount of manganese)
• Susceptibility to cracking from excessive stress
• Highly castable
• Above-average thermal conductivity
• Non-ferromagnetic (making it easier to separate for recycling)

Brass finds application across a wide range of industries, such as:

• The brighter, gold-looking appearance of brass makes it an excellent choice for decorative applications.
• Musical instruments. Its workability and durability make it a highly suitable source material for musical instruments (e.g., guitar strings)
• Plumbing pipes and tubing. The high corrosion resistance demonstrated by brass makes it suitable for plumbing applications.
• Similar to bronze, brass is used in electronic applications, due to its excellent electrical conductivity.

Property	Value
Chemical Symbol	Brass is an alloy, primarily composed of copper (Cu) and zinc (Zn)
Composition	Typically, brass contains around 60-80% copper and 20-40% zinc, with small amounts of other elements such as lead, aluminum, or tin for specific properties.
Density	Varies depending on the specific composition of the alloy, typically ranges from 8.4 to 8.7 g/cm³
Melting Point	Varies depending on the composition, typically between 900°C to 940°C (1652°F to 1724°F)
Young's Modulus	90–110 GPa (for common brass alloys)
Shear Modulus	33–40 GPa (for common brass alloys)
Bulk Modulus	100–140 GPa (for common brass alloys)
Poisson's Ratio	0.33–0.36 (for common brass alloys)
Tensile Strength	290–620 MPa (for common brass alloys)
Yield Strength	150–450 MPa (for common brass alloys)
Elongation at Break	10–40% (for common brass alloys)
Hardness (Brinell)	65–230 HB (for common brass alloys)
Electrical Conductivity	Brass has good electrical conductivity, typically around 23–45 MS/m (megaSiemens per meter) depending on the alloy composition and condition.
Thermal Conductivity	Varies depending on the composition, typically ranges from 100 to 130 W/(m·K) (Watts per meter-Kelvin) for common brass alloys.

Notes :

• The properties of brass can vary significantly depending on the specific composition of the alloy, including the percentage of copper, zinc, and any additional elements.
• Different brass alloys are engineered for specific applications, with variations in properties such as strength, corrosion resistance, machinability, and appearance.
• Brass is valued for its combination of properties, including its attractive appearance, corrosion resistance, malleability, and ease of machining.
• Common applications of brass include decorative items, musical instruments, plumbing fittings, electrical connectors, and various industrial components.
