Silver Braze 56Ni2

Silver Braze 56Ni2 Technical Data


Silver Braze 56Ni2 is a zinc free brazing alloy commonly used in flux free brazing of stainless steels in dry hydrogen atmosphere. Silver Braze 56Ni2 shows advantages in flux free furnace brazing applications where zinc voltilzation is objectionable.

Brazing Characteristics

Silver Braze 56Ni2 is an intermediate temperature silver brazing alloy. Silver Braze 56Ni2 has a rather long melting range (220F/125C) so that it will tend to liquate (separate high from low melting phases) if it is heated slowly through its melting range. However, the long melting range is useful when wide gap joints are brazed as it will bridge the gap and produce larger fillets than alloys with short melting ranges that are more fluid. Silver Braze 56Ni2 cna be brazed by both torch and induction as well as under a protective atmosphere.

Properties of Brazed Joints

The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design, metallurgical interaction between the base metal and filler metal. 


Silver Braze 56Ni2 conforms to American Welding Society (AWS) A5.8/A5.8M BAg-13a, Society of Automotive Engineers (SAE) AMS 4765

Available Forms

Silver Braze 56Ni2 is available in wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
