BVAu-10

BVAu-10 Technical Data

Uses

BVAu-10 can be used on any of the common ferrous and non-ferrous alloys. This alloy exhibits good wetting characteristics on metallized ceramics. Typical applications include brazing of electron tubes, vacuum tubes, radar devices, and wave guides in the electronic industry. This alloy is readily used in the brazing of ceramic to metal seals.

Brazing Characteristics

BVAu-10 is generally used in reducing, vacuum or inert atmospheres. It is a less ductile alloy than standard gold-copper-nickel alloys. The composition of the alloy allows for use in applications where braze filler metals low in volatile constituents are required. This alloy exhibits free flowing characteristics due to its narrow melt range.

Properties of Brazed Joints

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 gold base alloys fall within 0-0.002 in. (0-0.05 mm)
