Silver Alloy 30
AWS: BAg-2a
Silver Alloy 30 is a general purpose, low temperature silver base brazing filler metal used to join both ferrous and non-ferrous metals. because of their fairly low cost, good fatigue strength and ability to make leak-tight joints where close clearances cannot be maintained, it has been widely used in the refrigeration and air-conditioning industry.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
Characteristics
Silver Alloy 30 is a low temperature, economical, brazing filler metal capable of bridging gaps where tight joints fit-up cannot be maintained. Silver Alloy 30 has a tendency to liquate (separate into low and high melting constituents) when heated slowly and therefore it is preferable to use it where the heat source is sufficient to raise the part temperature rapidly through the melting range of the brazing filler metal. Silver Alloy 30 tends to liquate slightly more than Silver Alloy 35.
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.
