FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular to sintered friction materials based on copper for operation in friction units of machines and mechanisms in the presence of lubrication. Sintered friction material based on copper containing, wt%: tin 4-7, graphite 9-12, iron powder 27-30, aluminum nitride powder 1-3, copper - the rest. The particle size of aluminum nitride is 5-8 mcm.
EFFECT: increase in the coefficient of friction and the coefficient of thermal conductivity is provided.
