Abstract
Copper alloy castings are produced by adding 0,2-2,0 per cent of chromium to the copper with or without suitable deoxidants, casting the alloy and then heating the casting to 300-700 DEG C. The deoxidants employed are zinc-sodium alloy, cadmium sodium alloy or one or more of the substances calcium, silicon, beryllium, calcium boride or boron carbide and the metal may be covered with charcoal or a flux such as borax or glass during melting and casting. The chromium may be added to the copper in the form of a master chromium-copper alloy containing 10 per cent of chromium and one or more of the metals, lead, silver, zinc and cadmium in a total amount not exceeding 5 per cent may be added to the alloy before casting. In an example, an alloy contains in addition to the chromium content above 1 per cent of cadmium, 1 of zinc, 0,5 of lead and 0,10 of silver. The alloy castings may be used for the manufacture of electrical devices such as plugs, &c., casting moulds, parts of internal-combustion engines and twyers or other fittings of blast furnaces.
