FIELD: metallurgy.
SUBSTANCE: invention refers to antifriction alloys on aluminium base, mainly for parts operating under sliding friction. The alloy contains the following combination of elements, mas.%: silicon 4.0...7.0, copper 2.5...4.5, magnesium 1.9...3.0, zinc 0.3...2.5, tin 1.5...3.5, lead 0.7...1.8, manganese 0.3...0.7, titanium 0.15...0.25, zirconium 0.15...0.25, iron 0.3...0.7, aluminium - the rest; at that tin and lead are introduced into the alloy as an addition alloy tin-lead wherein the ratio of lead to tin is 0.47...0.51.
EFFECT: alloy possesses upgraded tribotechnical characteristics, excluding seizure and burrs, and upgraded characteristics of structural strength of the alloy.
