RIVETTING BRASS

BS 2872 CZ108, CZ 131:

British Standards specifying the composition and mechanical properties for different grades of leaded riveting brasses.

Properties:

1. Corrosion Resistance:
• Good general corrosion resistance, suitable for various industrial and commercial applications.
• Adequate resistance to dezincification, making it suitable for less aggressive environments.
Mechanical Properties:
• Tensile Strength:Typically around 350-450 MPa.
• Yield Strength: Approximately 100-200 MPa.
• Elongation: Generally around 30-45%, indicating good ductility
• Hardness: Moderate hardness, with a typical Brinell hardness number (HB) of around 80-120.
Machinability:
• Good machinability due to the presence of lead, making it suitable for machining and forming operations.
• Often used in the manufacturing of rivets and other fasteners.
Forgeability:
• Excellent formability, allowing for easy cold working processes such as riveting, bending, and stamping.
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:

Rivets: Extensively used in the production of rivets for various applications, including automotive, aerospace, and construction industries.
Fasteners: Commonly used in the manufacturing of various fasteners, such as bolts, screws, and nuts, due to its good machinability and formability.
Electrical Components: Employed in electrical connectors and terminals due to its good conductivity and ease of manufacturing.
Industrial Equipment: Suitable for various industrial equipment parts, including gears, valves, and connectors, where good formability is required.
