Abstract
PURPOSE: To inexpensively obtain an electrical contact material for sealing with superior melt-sticking resistance, superior hardly dissipative property and low contact resistance characterisitc by mixing copper with manganese oxide in a specified ratio.
CONSTITUTION: A mixture consisting of 3W15wt% manganese oxide and the blance copper is compressed to form a green compact, and the compact is sintered at about 900°C in a vacuum and repeatedly subjected to working and heat treatment to manufacture an electrical contact material. To the copper- manganese oxide may be added a small of iron, nickel, cobalt, chromium, titanium or oxide thereof.
