ABSTRACT:
Composite electrical contact composed of a copper base portion clad with a contact portion of Ag-SnO alloy. The contact and base portions are fusion bonded by an interfacial alloy layer of Ag and Cu and an adjacent diffusion layer of Cu as the result of heat-treatment of the contact at the eutectic temperature of Ag and Cu.
