Abstract
A friction material especially for use in conjunction with aluminum alloy brake rotors containing silicon carbide particles contains 15 to 80% of a finely divided alumina abrasive, from 5 to 40% of cured organic binder, less than 5% metal in particulate form and less than 5% particulate carbon and/or graphite, from 1 to 40% of organic fiber the balance being particulate inert filler and optionally, a non-graphitic lubricant, all percentages being by volume.

A friction material consisting essentially of:
- (a) 15 to 80% by volume of finely divided abrasive alumina having a majority of particles in the range 1-10 microns,
- (b) 5 to 40% by volume of organic binder,
- (c) 1-40% by volume organic fiber,
- the balance being particulate non-metallic inert filler and optionally, non-graphitic lubricant.
