FIELD: production of friction materials. SUBSTANCE: friction material on the base of light metals contains zinc and magnesium alloy (4 mass % ), phenol resin (35 mass % ), carbon fiber (25 mass % ), silicium carbide (15 mass % ) and barite concentrate (the rest) as additives. Above mentioned zinc and magnesium alloy contains 54 mass % of zinc. Thus prepared powdery alloy has melting point 320-380 C, its secretary heat of infusion is higher 15 cal/g, energetic wear being 2,5×10-7 см3/J. EFFECT: improves alloy quality. 1 tbl
