Cu-Cr-BASED COPPER ALLOY FOR ELECTRONIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a Cu-Cr-based copper alloy with which the characteristics are tremendously improved by demonstrating the effectiveness of Cr addition better. SOLUTION: The Cu alloy for electronic material is the Cu alloy constituted of 0.04-0.50% Cr and the balance Cu with inevitable impurities and the content of carbon is≤50 ppm by volume.
