Lucas-Milhaupt HI-TEMP® 720 General-Purpose Nickel Brazing Alloy (AWS BNi-1)
Categories:	Metal; Nonferrous Metal; Precious Metal; Palladium Alloy; Solder/Braze Alloy
Material Notes:	Hi-Temp 720 is a general-purpose nickel brazing alloy which can be used for a wide variety of applications. Typically, this alloy is used for joining super alloys, stainless steels, and alloys requiring good joint strength at high temperatures while maintaining good corrosion and oxidation resistant characteristics. Hi-Temp 720 exhibits excellent flow characteristics when tighter clearances are maintained. Minimizing joint clearances and the amount of material applied will limit the amount of erosion into the base metal. Available forms: Powder and paste. Information provided by Lucas-Milhaupt.
