Aufhauser SilverAlloy A-38T has similar melt temperatures to cadmium-containing alloys SilverAlloy Cd-30 and SilverAlloy Cd-35. The tin content provides good wetting on many difficult to wet metals such as stainless steel and tungsten carbide.
The tin content provides good wetting on many difficult to wet metals such as stainless steel and tungsten carbide. This alloy, being free of lead (Pb) or cadmium (Cd) is preferred for long heating cycles and is suitable for use in controlled atmosphere brazing without flux. Typical applications are the joining of ferrous, nonferrous and dissimilar metals and alloys with close joint clearances. SilverAlloy A-38T is used for joining ferrous metals (stainless steel, tungsten or molybdenum carbide), and nonferrous (copper, copper alloys, nickel, nickel alloys). The largest use of this alloy is for furnace brazing although it is also suitable for other brazing procedures.
