FIELD: metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular to friction materials designed to work in friction units of machines and mechanisms in the presence of lubrication. Copper-based sintered material containing tin, graphite, iron powder, additionally contains silicon oxide powder with fraction of 5–10 mcm, with the following ratio of components, wt%: tin — 4–7, graphite — 9–12, iron powder — 27–30, silicon oxide powder — 2–4, copper — the rest.
EFFECT: higher friction coefficient, higher stability of moment of friction, reduced pressure of formation of oil draining channels and grooves in process of material plastic deformation, increased strength of friction material connection with steel base, as well as efficiency of running-in.
