ChannelFlux Silver® A-50N

ChannelFlux® Silver A-50N offers good strength and flow characteristics and works well on stainless steel and carbide. The base alloy, 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 retard joint or interface corrosion of the brazed assembly. The nickel element in ChannelFlux Silver A-50N also improves the bond strength when joining of tungsten carbide cutting tips. ChannelFlux Silver A-50N is a suitable replacement to the cadmium containing BAg-3 alloy, with the added benefit of flux integration! Its low liquidus of 1305 ºF reduces surface oxidation and sensitization to stainless steels.

A good replacement to Brazeit 50N and a flux integrated option to A50N in attaching carbides. Used with 300 series stainless in Food, Medical, and Dental fields. Good replacement of 50N or A50N in carbide brazing.

Available Forms

Standard forms of ChannelFlux Silver A-50N are brazing wire, brazing rod, 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.
