Heat Resistant Copper Alloys (Zharoprochnye Mednye Splavy),
Abstract
A study was made on heat resistance, rigidity, and stability at 400C of a number of copper alloys (Cr, V, Ce, Zr and others). Zr produced the greatest increase in heat resistance; cerium and calcium improved heat resistance, but not as much as zirconium. The hardest copper alloys produced were Cu-Zr-Ce and Cu-Cr-V. Alloys of 2-3% Zr or 1.5-20% (Zr + Ce) proved to be pliable with a good combination of heat resistance and electrical conductibility (not less than 75% of the conductivity of Cu). Stress-rupture strength at 400C or 100-hour tests was 12-13 kg (force)/sq mm (3-4 times greater than the stability of Cu) and at 600 C, 2.8-3.3 kg (force)/sq mm. (Author)
