Abstract

Commercial nickel or cobalt containing above 0,2 per cent of carbon is decarburized by heating to a temperature above 1000 DEG C. and below the melting point, preferably not over 1300 DEG C., in a non-reducing, preferably an oxidizing, atmosphere, so that the final product contains less than 0,05 per cent of carbon. The final product may be used for the production of ferro-alloys which are as free from carbon as possible. In an example an alloy produced contains 0,02 per cent of carbon, 49,5 of iron 5 of copper, 10 of aluminium, 22,5 of nickel and 13 of cobalt.
