FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular, to friction materials based on copper. It can be used to work in conditions of liquid friction of components and mechanisms, automotive and special-purpose machinery. The composition of sintered friction material based on copper contains, wt. %: tin 4-7, graphite 7-9, iron 30-35, sulfur 5-7, copper the rest.
EFFECT: reduction in the run-in period of the sintered friction material is provided, a reduction in the stamping pressure during the manufacture of the friction disc.
