WELDABLE ALLOY BASED ON ALUMINIUM FOR METEOROID PROTECTION

摘要

FIELD: metallurgy.;SUBSTANCE: alloy contains wt %: zinc 2-8.5, magnesium 1.5-3.5, manganese 0.1-0.5, chromium 0.05-0.3, zirconium 0.05-0.3, hafnium 0.05-1.5, beryllium 0.0001-0.01, at least one element from the group: copper, titanium, nickel, cobalt up to 0.30 each, aluminium and inevitable impurities in an amount not exceeding 0.7 are the rest.;EFFECT: due to uniform grain structure provides high resistance to impact with increase in strength, satisfactory ductility and weldability.;3 cl, 5 ex, 2 tbl, 6 dwg
