RBCuZn-D (Nickel Silver)
Alloy Type: A5.8, BRAZING Filler Metals
RBCuZn-D Nickel Silver (RBCuZn-D) is a bare or flux coated 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.
Typical Applications:
Brazing tungsten carbides, copper alloys, nickel alloys, stainless and carbon steel; building up and/or overlaying worn parts such as gear teeth, bearings, and valve seats; brazing steel or cast iron where good color match is desired
