Abstract

PURPOSE: To inexpensively obtain an electrical contact material for sealing with superior melt sticking resistance and low contact resistance characteristics by mixing copper with cobalt oxide in a specified ratio.
CONSTITUTION: A mixture consisting of 5W20wt% cobalt oxide and the balance copper is compressed to form a green compact, and the compact is sintered at about 850°C in a vacuum and repeatedly subjected to working and heat treatment to manufacture an electrical contact material. To the copper-cobalt oxide may be added a small amount of iron, nickel, chromium, manganese, titanium or oxide thereof.
