Silver Braze 45

Silver Braze 45 Technical Data


Silver Braze 45 has been used for brazing of tubular assemblies in the ship construction industry. Other applications may include brazing of musical brass instruments, brass lamps, aircraft engine oil coolers. Silver Braze 45 is a general purpose, brazing filler metal for use where cadmium free filler metal is required.

Brazing Characteristics

Silver Braze 45 is an intermediate temperature cadmium free silver brazing filler metal with sufficient melting range (145°F/63°C) to properly braze joints with the range of fits encountered in commercial tubing and fittings. It has a slight tendency to liquate (separation into high and low melting constituents) if heated slowly through its melting range.

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 45 conforms to American Welding Society (AWS) A5.8/A5.8M BAg-5

Available Forms

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