Abstract
578,873. Alloys ; heat-treating and working. COOK, M., ALEXANDER, W. O., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 17, 1941, No. 13376. [Classes 72 and 82 (i)] [Also in Group XXII] Condenser tubes, ferrules, &c. are made from copper zinc aluminum alloys covered by the triangle A, B, C, in the Figure, the alloys being retained completely in the alpha phase by effecting all necessary hot-working and annealing treatments at 500-650‹ C., preferably at 600‹ C. The alloys may also contain a small proportion of an agent to reduce or prevent zincification, e.g. 0.02-0.06 per cent of arsenic and may also contain up to 0.5 per cent of each of one or more of iron, silicon, phosphorus, cadmium, silver, tin, lead and nickel, the total amount of these elements not exceeding 2 per cent.
