Gold Braze 2575
Gold Braze 2575 can be used on any of the common ferrous and non-ferrous alloys. This alloy exhibits good wetting characteristics on metallized ceramics. Typical applications may include brazing of electron tubes, vacuum tubes, and wave guides in the electronic industry. Gold Braze 2575 may also be used in brazing of ceramic to metal seals.
Available Forms
Wire, strip, engineered preforms and specialty preforms per customer specification, powder and paste.
Characteristics
Gold Braze 2575 is generally used in reducing, vacuum, or inert atmosphere. 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. Due to its narrow plastic range, Gold Braze 2575 exhibits free flowing characteristics.
Properties
The properties of a brazed joint are dependent upon numerous factors including base metal properties, joint design and brazing technique. For controlled atmosphere brazing or vacuum brazing the recommended radial joint clearance for gold base alloys fall within 0.000in – 0.002in (0.00mm-0.05mm) range.
