Silver Braze 49Ni4
AWS: BAg-22
Silver Braze 49Ni4 has excellent wetting properties. It is used extensively for brazing tungsten carbide inserts to cutting tools and rock drills. It may be used for joining all types of stainless steels and carbon steels.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste. *TRI49Ni4 is only available in strip and stamped preforms due to its layered design.
Characteristics
Silver Braze 49Ni4 is a cadmium-free, low temperature brazing filler metal used for brazing of tungsten carbides, steels and stainless steels. Because of its high manganese content, Silver Braze 49Ni4 may tend to liquate (separation into low and high melting constituents). However this can be mitigated by rapidly heating the joint assembly through the melting range of Silver Braze 49Ni4. Flux may be used, but on some more of the more difficult to braze alloys, such as carbides and stainless steels, flux assists in producing better wetting of the joint surfaces.
Properties
The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design, metallurgical interaction between the base metal and the filler metal. The results listed below were generated from brazed butt joints which were tested under standard room temperature conditions.
