Abstract

PURPOSE: To enhance the fusion and consumption resistances of an electrical contact material by making the material of alloy of a speficied compsn. consisting of tin oxide, lead oxide, zinc oxide, nickel oxide, silver, etc.
CONSTITUTION: The alloy consists of, by wt., tin oxide 4W8% as metallic tin, lead oxide 0.01W1% as metallic lead, zinc oxide 0.1W2% as metallic zinc and the balance silver. Nickel oxide 0.01W1% as metallic nickel may be added to the alloy. By the synergistic effect of zinc and nickel, the grains are refined, and fine oxides are precipitated in the grains, resulting in uniform dispersion. Thus, the fusion and consumption resistances of the electrical contact material are improved furthermore.
