ABSTRACT:
Metal composites comprising a metallic matrix and discrete, non-metallic solid particles are useful as friction materials, and may be die-cast to form friction elements. The preferred metallic matrix components are alloys containing aluminum such as aluminum-silicon and aluminum-silicon-zinc alloys.
