Abstract
172,018. Johnston, R. L., Archer, R. S., and Jeffries, Z. Nov. 27, 1920, [Convention date]. Alloys.-An aluminium alloy contains about 3-10 per cent of silicon and also copper or zinc or both. When zinc is present an alkali metal or metals may also be added. Iron, preferably not exceeding 0.6 per cent may also be present. Alloys containing (1) aluminium, silicon and 2-5 per cent of copper; (2) aluminium, an alkali metal, about 8 per cent of silicon and about 10 per cent of zinc; and (3) 8 per cent of silicon, 10 per cent of zinc, and 2.5 per cent of copper, are referred to. Some of the alloys may be subjected to the heat-treatment described in Specification 173,746.
