Abstract
257,891. General Plate Co., (Assignees of Davignon, V. D.). Sept. 4, 1925, [Convention date]. Alloys.-Gold alloys, containing about 25-85 per cent of gold, contain also 1-10 per cent of aluminium, and sufficient base metal or metals, generally consisting of or including copper, to render them malleable and ductile. In making the alloys, the molten metal is protected from atmospheric oxidation, for example by means of sufficient flux, which may consist of potassium bifluoride and calcium chloride, to form a layer thereon, the metal and flux being then poured into the mould. Examples contain (1) 14 parts of gold, 6 parts of copper, 3 parts of zinc, and 1 part of aluminium; and (2) 58 per cent of gold, 5 per cent of aluminium, and 37 per cent of copper, or of copper along with other metal or metals such as zinc, nickel, and silver.
