Material Notes:
Silvaloy 30 is historically a modification of Silvaloy 35 with further reduction in silver content resulting in a higher melting point and a longer range. Silvaloy 30 is used for brazing steel, stainless steel, copper, copper alloys, nickel, nickel alloys or combinations of these metals. It is similar to Silvaloy 35 in performance although it contains less silver. Its broader melting range is helpful where clearances are not uniform. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances.Information provided by Lucas-Milhaupt Warwick, LLC (formerly Wolverine Joining Technologies).
