FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, particularly to antifriction alloy based on zinc-tin-aluminum, and can be used in production of explosion-proof products for various purposes. Antifriction alloy based on zinc-tin-aluminum contains, wt%: tin – 18.0–20.3; aluminum – 10.5–12.1; copper – 3.8–5.6; silicon – 0.05–0.075; iron – 0.01–0.5; lead – 0.01–0.02; cadmium – 0.012–0.16; zinc – balance.
EFFECT: alloy is characterized by high strength, relative elongation, hardness, and low risk of fire and explosion.
