FIELD: alloys. SUBSTANCE: aluminium-base casting alloy has, wt.-% zinc 3.2-3.8; magnesium 2.2-2.8; titanium 0.1-0.3; chrome 0.1-0.3; zirconium 0.1-0.3; beryllium 0.01-0.05, boron as additional component 0.01-0.03, and aluminium the rest. Properties of welded articles: strength limit is 324-327 MPa, relative elongation is 8.3-10.0% hot-shortness is 15.0 mm. Alloy does not show tendency for corrosion cracking, time before crack formation is below 90 days. EFFECT: enhanced mechanical and anticorrosion properties, decreased hot-shortness of alloy. 2 tbl
