Abstract
Cast alloy magnets consisting of 6-15 per cent of aluminium, 12-30 per cent of nickel, 0,5-10 per cent of cobalt and the remainder iron are made by melting the ingredients, casting the alloy, normalizing the casting at 1000-1500 DEG C., cooling the casting, and then ageing it at 500-700 DEG C. Specification 423,897 is referred to.
