FIELD: metallurgy.
SUBSTANCE: alloy includes the following component ratio, wt %: lead 20-40, zinc 5-15, and aluminium is the rest. An alloy obtaining method involves preparation of a hetero-phase alloy based on aluminium with 20-50 wt % of zinc, which is obtained by continuous mixing of the melt at 700°C during 10 minutes and quick cooling of the melt on a water-cooled copper plate, and contact of the obtained workpiece of the hetero-phase alloy to the lead melt at 530-570°C.
EFFECT: increasing strength and hardness of an alloy at reducing linear wear and friction coefficient.
