ABSTRACT:
This invention relates to metal matrix composites containing at least 40% v/v of a hard material such as SiC and a matrix of aluminium, magnesium or alloys of either. The invention also covers a method of making such composites by ball milling powders of the respective components. Other mixing techniques do not enable such a high proportion of hard material to be incorporated into the composite. The composites are useful to produce components resistant to wear.
