Silver Braze 45T

Silver Braze 45T Technical Data


Silver Braze 45T is a general purpose, low temperature filler metal used in cadmium-free brazing applications. It offers an excellent compromise between low melting point and moderate silver content. For improved corrosion resistance in stainless steel joints, use an alloy that contains a small amount of nickel.

Brazing Characteristics

Silver Braze 45T is a free-flowing, low temperature filler metal commonly used as a replacement of cadmium-bearing filler metals of similar silver content. This alloy is best suited for narrow gap applications (0.001in. – 0.005in radial joint clearance). Flux should be used with this alloy.

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 the filler metal.


Silver Braze 45T conforms to American Welding Society (AWS) A5.8/A5.8M BAg-36

Available Forms

Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
