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 Tin Bronze GK

Alloying and atomization of copper and tin in air produces irregularly shaped bronze powder. Deoxidizing components (e.g. phosphorus) can be added to produce powders with light gloss, e.g. those needed in filter materials.

A standard alloy contains approx. 90% copper and 10% tin. Special alloys and the respective particle size distribution are part of the individual specifications and are ensured through effective process and quality control.
