ALUMINUM-BASE CASTING ANTIFRICTION ALLOY Russian patent published in 2004 - IPC

FIELD: non-ferrous metallurgy. SUBSTANCE: invention can be used in casting manufacturing in preparing aluminum alloys, for example, for preparing different members in machine engineering, motor manufacturing and other branches of technique. Invention proposes alloy comprising the following component, %: silicon, 2.5-4.0; copper, 5.5- 7.0; lead, 1.0-7.0; iron, up to 0.5; magnesium, up to 0.35; aluminum, the balance. Invention provides the improvement of resistance to wear and strength of alloy under conditions of slipping friction. EFFECT: improved properties of alloy, reduced price in alloy preparing. 1 tbl, 1 ex
