Material Notes:
Silvacote A50N Flux Coated Rod is a cadmium free silver brazing alloy that has found numerous applications for joining 300 series stainless steel in food, medical, and dental fields. 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 Silvacote A50N also improves the bond strength when joining the tungsten carbide cutting tips. Typical applications are the joining of 300 series stainless steels in the food, medical, and dental fields.Information provided by Lucas-Milhaupt Warwick, LLC (formerly Wolverine Joining Technologies).
