SILVER ALLOY MATERIAL AND METHOD FOR MANUFACTURING THE SILVER ALLOY MATERIAL

摘要

The present invention provides a silver alloy material and a method for manufacturing the silver alloy material, the silver alloy material comprising essentially by weight of about 65% to 95% Ag, about 5% to 35% In. The silver alloy material has a solid-liquid coexistence zone. The steps for manufacturing the silver alloy material include mixing, heating in vacuum status, cooling and annealing. The characters of the silver alloy are low yield tensile strength (58 Mpa), high ultimate tensile strength (300 MPa) and high elongation (60%) and anti-tarnishing property. The silver alloy material could be used for optics reflector mirror, silver ornament, brazing materials and very fine silver alloy wire for semiconductor bounding application.
