RBCuZn-D (Nickel Silver)

< CLICK HERE for additional information on this alloy >

 

RBCuZn-D Nickel Silver (RBCuZn-D) is a bare 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
