Material Notes:
Silvaloy A56T Flux Cored has the lowest brazing temperature, best wetting, and best flow of all the cadmium free alloys. It has a slight plastic range which may be noticed during melting on some applications. Its low zinc content minimizes problems due to longer heating cycles or due to excessive heating. It is often selected for use on silver or stainless steel due to its excellent color match. Typical applications are the joining of ferrous, non-ferrous, and dissimilar metals and alloys with close joint clearances.Information provided by Lucas-Milhaupt Warwick, LLC (formerly Wolverine Joining Technologies).
