Cadmium Free Brazing Alloys

An excellent substitute for Brazeit #50N. It offers good strength and flow characteristics and works well on stainless steel and carbide. Brazeit A-50N is a silver brazing alloy that has found numerous applications for joining 300 series stainless steels in the food, medical and dental fields. The absence of cadmium in the alloy permits direct contact to food and for various medical or hospital applications. Addition of nickel to the silver-copper zinc alloy imparts corrosion properties which retards joint or interface corrosion of the brazed assembly. The nickel element in Brazeit A-50N also improves the bond strength when joining of tungsten carbide cutting tips. Brazeit A-50N is a suitable replacement to the cadmium containing BAg-3 alloy. Its low liquidus of 1305 ºF reduces surface oxidation and sensitization to stainless steels.
