Friction linings

Copper and copper alloy powder, copper powder, bronze powder, brass powder

The thermal conductivity of metals is used in friction linings (brake and clutch linings) in order to dissipate the frictional heat generated during the braking process and to give the material the required strength. Depending on the type of vehicle, there are resin bonded friction linings (light vehicles) or sintered friction linings (heavy vehicles).

Rogal Brass

Brass is an alloy made of copper and zinc in various compositions.

Air atomization of the molten material results in irregularly shaped powders. Common compositions are brass I (approx. 92%Cu/8%Zn), brass II (approx. 82%Cu/18% Zn) and brass III (approx. 70%Cu/30%Zn)
