Abstract
Aluminium alloy for coating surfaces of low grade aluminium and other metallic or non-metallic bases and which can be electropolished (see Group XXXVI) consists of aluminium of at least 99.8 per cent purity with addition of 0.4 to 2 per cent and preferably 0.4 to 1 per cent of copper dissolved as completely as possible therein, e.g. as by annealing and then colding quickly or quenching, and may be with the addition of up to 1 per cent and preferably from 0.2 per cent to 0.6 per cent of magnesium and less than 0.2 per cent in total of iron and silicon. In an example, the alloy consists of aluminium of highest purity containing a total of iron and silicon of lower than 0.01 per cent with addition of 0.5 per cent of copper and 0.3 per cent of magnesium.
