Friction Materials

Sintered metal friction components are particularly useful for heavy-duty applications like aircraft brakes, heavy machinery clutch and brake linings, railway brake pads,...

They consist essentially of a continuous metal matrix, into which varying amounts of non-metallic friction generators, such as silica and emery, are bonded.

Compositions tend to be complex in terms of the characteristics required and may include copper, tin, iron, lead, graphite, carborundum, silica, alumina, emery, and asbestos substitutes.
The sintered material has a high thermal conductivity and may be used over a wide range of temperatures.
