BVAg-0
AWS: BVAg-0
BVAg-0 has a higher level of Ag than commercially pure fine silver, which by definition contains a minimum of 99.9% versus at least 99.95% Ag in BVAg-0. It is widely used in the electrical and electronics industries as contacts and conductors and in the chemical industry as linings for reactors and process/storage vessels, particularly caustic evaporators and crystallizers. BVAg-0 provides strong, ductile joints with good corrosion resistance.
Available Forms
Wire, strip, engineered preforms and specialty preforms per customer specification, powder and paste.
Characteristics
BVAg-0 is not an alloy – so it has a specific melt temperature, allowing it to easily fill tight joint clearances. It wets to most ferrous and nonferrous metals. It can have a tendency to flash across the base parts if left at braze temperature for too long.
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.
