Features and Benefits:
Blue Demon Flux Coated Nickel Silver also known as Nickel Bronze, (RBCuZn-D) is a brazing rod used widely as a replacement for high cost silver brazing alloys when higher brazing temperatures are acceptable.
The weld deposits have a very high tensile strength, good ductility and excellent corrosion resistance.
Nickel Silver weld deposits are also readily machinable and will not work harden when put into service.
A neutral or slightly oxidizing flame is recommended.
Applications:
Brazing tungsten carbides, copper alloys, nickel alloys, stainless and carbon steels.
Brazing steel or cast iron where good color match is desired.
Building up and/or overlaying worn parts such as gear teeth, bearings, and valve seats.
