VACUUM CIRCUIT BREAKER CONTACTS CONSISTING ESSENTIALLY OF A COPPER MATRIX AND SOLID SOLUTION PARTICLES OF COPPER-TELLURIUM AND COPPER-SELENIUM
First Claim
1. A vacuum circuit breaker having a pair of contact members relatively movable for contact and separation, where in at least one of the paired contact members is made of an alloy consisting essentially of a copper matrix and solid solution particles of a Cu2Te-Cu2Se system dispersed in said copper matrix, the content of selenium ranges between 0.1 and 5 percent on the basis of the alloy and that of tellurium ranges from 0.1 to 25.9 percent on the basis of the alloy, the total content of the selenium and tellurium being 2.5 to 26 percent on the basis of the alloy.
