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.

2020-5-28 Advantage #3 – Composite liners have a shorter delivery time. Due to the high production loss experienced every time a mill is shutdown, it’s critical that mill liner deliveries are consistently on time to allow for inspection and preparation ahead of the mill stoppage. Composites are quicker to manufacture, which results in shorter lead times.
