Lucas-Milhaupt PREMABRAZE® 51 Gold-Copper Braze Alloy
Categories: Metal; Nonferrous Metal; Precious Metal; Gold Alloy; Solder/Braze Alloy

Material Notes: Premabraze 051 can be used on any of the common ferrous and non-ferrous base alloys. Due to its low and narrow plastic range, this alloy is a preferred choice in step brazing operations. Premabraze 051 exhibits excellent vacuum properties along with high corrosion and oxidation resistance properties. Premabraze 051 is a modified gold-copper alloy. It is generally used in reducing, vacuum, or inert atmosphere. It is a more ductile alloy than standard gold-copper alloys. The composition of the alloy allows for use in applications where braze filler metals low in volatile constituents are required.

Available forms: Wire, strip, engineered preforms, specialty preforms, powder and paste.
