Silver Braze In15 VG
AWS: BVAg-29
Silver Braze In15 is used in a wide range of moderate temperature low pressure systems, and is found quite often in electronic vacuum tube applications.
Available Forms
Wire, strip, engineered preforms, specialty preforms per customer specification, powder and paste.
Characteristics
SBIn15 is a low temperature vacuum-grade filler metal which has a tendency to liquate when heated at a slow rate due to its large melt range. SBIn15 is designed for all types of moderate temperature vacuum systems and particularly where maximum precautions must be taken to ensure the presence of only a minimum amount of detrimental volatile impurities. It can be brazed successfully under hydrogen, inert or vacuum atmospheres without the use of flux. The indium content aids in wetting to the surface of ferrous alloys compared to silver-copper-zinc systems.
Properties
The properties of a brazed joint are dependent upon the base metal, joint design and brazing technique. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for silver base alloys falls within 0.000in – 0.002in (0.00mm – 0.05mm) range.
