Abstract

521,733. Alloys; annealing. M A L L O R Y METALLURGICAL PRODUCTS, Ltd. (Mallory & Co., Inc. P. R.). Nov. 26, 1938, No. 34490, [Classes 72 and 82 (i)] An age-hardenable copper alloy particularly for welding electrodes and electric contacts contains 0 05 - 3 per cent. of beryllium, 0À05 - 4 per cent. of silver, and 0À05 - 10 per cent. of nickel. Small amounts of one or more of the following elements may be present as impurities : silicon, zirconium, zinc, cadmium, aluminium, and lithium. Heat - treatment, which may follow hot working may comprise quenching the cast material from 700-900‹C. and ageing at 250- 600‹C. The material may be cold worked after ageing.
