Abstract
A dry friction material comprises fiber base material, bonding agent, friction conditioner and filler. The dry friction material contains 2 to 20% by weight of a tin alloy in which the fusing point is more than 500.degree. C. and the hardness is less than 4 Moh's. The dry friction material shows excellent friction characteristics when the load is low or average.
