PROTECTOR ALLOY BASED ON ALUMINIUM

摘要

The invention relates to non-ferrous metallurgy and concerns protector aluminium alloy for the protection against corrosion of steel structures and buildings in aggressive media. The alloy contains, % by weight : zinc - 1.40-6.80; calcium - 1.30-3.00; manganese - 0.10-0.62; iron -0.01-0.17; silicon - 0.01-0.16; copper - 0.009-0.010; vanadium -0.005-0.020; aluminium is the rest. Technical result: E x.c.e. in 3 % solution of NaCl is of -0.96 ?-1.10 V; efficiency factor is of 70-94 %.
