Sunraj Industries exports Silver Copper Zinc Brazing Alloys which provide perfect performance with low melting point, extensive flow properties and creating strong, ductile, rustresistant joints of excellent conductivity. Suitable for joining all non-ferrous metals and ferrous metals except Aluminium and Magnesium. Flux is needed for Brazing except for in protective atmosphere of vacuum brazing. The addition of Zinc/Tin can help as temperature depressant and reduce cost of filler metal. Nickel can improve the heat-resisting, rust-resisting and wetting properties of the alloy.
