CAST ALLOY ON ALUMINIUM BASIS AND PRODUCT MADE OF IT

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to production of the shaped castings out of the alloy of the aluminium basis of system Al-Si-Cu-Mg, used as base parts of the control devices of the fuel system in aviation, vehicles construction and other industries. The cast aluminium-based alloy contains, wt %: silicon 7.0-12.0; copper 1.0-3.5; manganese 0.1-0.9; titanium 0.01-0.4; zirconium 0.01-0.4, scandium 0.01-0.5; aluminium - the rest.EFFECT: exclusion of alloys embrittlement of aluminium basis, reduced metal content, wastes, simple production process.2 cl, 3 ex, 2 tbl
