An excellent substitute for #50N. It offers good strength and flow characteristics and works well on stainless steel and carbide. #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 #A-50N also improves the bond strength when joining of tungsten carbide cutting tips. #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.

Typical applications are the joining of 300 series stainless steels in the food, medical, and dental fields. A good replacement to #50N in attaching carbides.

Used with 300 series stainless in Food, Medical, and Dental fields. Good replacement of Sil. 50N in carbide brazing.

Available Forms

Standard forms of #A-50N are brazing wire, brazing strip, and brazing preforms.

Safety Information

It is essential that adequate ventilation be provided so that personnel will not inhale gases and fumes while brazing equipment or facility should conform to the provisions of American National Standard (ANSI) Z49.1, "Safety in Welding and Cutting." For more complete information, refer to the Material Safety Data Sheet for Brazeit A-50N.
