IN 1982 CC491K | CuSn5Zn5Pb5

B5 | Bronze Copper Alloy Tin Zinc

Available formats: Bars, Tubes, Caps, Plates and Plates.

features

Copper B5 is a base alloy CuSn noted for its excellent properties of toughness, toughness, wear resistance, corrosion and elasticity. They need to have good lubrication, which allows them to work with high specific loads. Tin copper alloy also known as red bronze or leaded gunmetal.

 

The closest international standards are the BS 1400 LG2, the ASTM B505 C83600 and the CuSn5ZnPb (Rg5).

 

It has good machinability and offers good corrosion resistance. We have stock in hollow bars, solid bars, rectangular plates and is available in other forms upon customer request.

Applications

It must be used for bushings and parts of current use with moderate loads and speeds.

 

Typical applications: Lubricated parts with high load, impact and coupling. Serrated parts of high request. Crowns, Gears, Bearings, Shirts, Nuts, Screws, Worm, Balancines, Friction Rings and Nuts, Connecting Rod Bushings, Presses, Cranes, etc.
