FORGING BRASS

ASTM B 124 C37700:

ASTM standard specifying the composition and mechanical properties for leaded forging brass.

BS 2874 CZ 122:

British Standard specifying the requirements for leaded forging brass alloys.

IS 3488 Forging Brass:

Indian Standard specifying the composition and properties for leaded forging brass.

CW 608N:

European standard specifying the composition and properties for leaded forging brass alloys.

Properties:

1. Corrosion Resistance:
• Good general corrosion resistance, suitable for many industrial and commercial applications.
• Moderate resistance to dezincification, not typically suitable for highly aggressive environments.
Mechanical Properties:
• Tensile Strength:Typically around 350-450 MPa.
• Yield Strength: Approximately 100-250 MPa.
• Elongation: Generally around 20-30%, indicating good ductility
• Hardness: Moderate hardness, with a typical Brinell hardness number (HB) of around 80-120.
Machinability:
• Excellent machinability due to the presence of lead, making it ideal for high-speed machining and turning operations.
• Often used in automatic screw machines and other machining equipment.
Forgeability:
• Good forgeability, allowing for the production of complex shapes and high-strength components.
• Suitable for hot forging processes.
Thermal and Electrical Conductivity:
• Good thermal conductivity, suitable for heat exchange applications.
• Moderate electrical conductivity, sufficient for many industrial uses but lower than pure copper.

Applications:

Forged Components: Extensively used in the production of precision forged components, such as fittings, connectors, valves, and fasteners.
Plumbing Systems: Commonly used in domestic and commercial plumbing systems due to its forgeability and corrosion resistance.
Automotive and Aerospace: Employed in the automotive and aerospace industries for components requiring precise forging and reliable performance.
Industrial Equipment: Suitable for various industrial equipment parts, including gears, bearings, and bushings, where precise machining and forging are required.
