Material Notes:
Silvaloy A20 can be used in a wide variety of applications but is infrequently used because of its relatively high melting point. It is an excellent choice when simultaneously brazing and heat treating carbon steel because of the close temperature match. It is also widely used on yellow brass assemblies because of the close color match. Generally, the strength of Silvaloy A20 will surpass the strengths of the base metals.Information provided by Lucas-Milhaupt Warwick, LLC (formerly Wolverine Joining Technologies).
