TRI50Ni2
AWS: BAg-24
Trimetal 50Ni2 is a three-layer composite metal consisting of a copper core faced on each side with SB50Ni2; the relative thickness of the 3 layers is in a 1/2/1 ratio. This layered design is beneficial for carbide tool inserts because the increased ductility of the copper core minimizes internal stresses introduced by differences in thermal expansion between the carbide and tool shank.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste. *TRI50Ni2 is only available in strip and stamped preforms due to its layered design.
Characteristics
Trimetal strip may also be used to braze aluminum-bronze to steel; the copper core acts as a barrier which prevents aluminum from migrating to the steel surface and adversely affecting the wetting of the SB50Ni2 to the steel surface.
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. Tensile Strength (lbs/in2) 18-8 Stainless Steal (annealed): 69,500-88,000 1029 Carbon Steel (Cold Worked): 66,000-73,300 Elongation (%, 2” gage length) 18-8 Stainless Steal (annealed): 1-9 1029 Carbon Steel (Cold Worked): 15-25
