Lucas-Milhaupt PREMABRAZE® 402 Gold-Copper Braze Alloy (AWS BVAu-10)
Categories:	Metal; Nonferrous Metal; Copper Alloy; Solder/Braze Alloy
Material Notes:	Premabraze 402 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. Premabraze 402 is readily used in the brazing of ceramic to metal seals. Premabraze 402 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. Due to its narrow plastic range, Premabraze 402 exhibits free flowing characteristics. Available forms: Wire, strip, engineered preforms, specialty preforms, powder and paste. Information provided by Lucas-Milhaupt.
