On Heat-Treatable Copper-Chromium Alloy (II)

Shigeyasu Koda and Eiji Isono


Abstract:

(1) As given in Part I of our report, we obtained a copper-chromium wire with a conductivity of 86%, a tensile strength of 62 kg/mm2 and an elongation of 2% by the following process-quenching, drawing, tempering and drawing again. (2) In this report, we describe how, to obtain better properties, we prepared wire rods with 0.86% of chromium, and quenched them, cold-drawn, tempered, cold-drawn and tempered again under several different conditions. (3) As the results of this research, we could obtain a wire with a conductivity of 80 ∼ 82%, a tensile strength of 65 ∼ 67 kg/mm2 and an elongation of 4 ∼ 6%.
