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 forcesq mm 3-4 times greater than the stability of Cu and at 600 C, 2.8-3.3 kg forcesq mm. Author
