Material Notes:
Silvaloy A34T is used for joining ferrous metals, copper, copper alloys, nickel, nickel alloys and combinations of these metals. The tin content provides good wetting on many difficult wet metals such as stainless steel and tungsten carbide. This alloy, being free of Pb or Cd is preferred for long heating cycles and is suitable for use in controlled atmosphere brazing without flux. The largest use of this alloy is for furnace brazing although it is also suitable for other brazing procedures. 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).
