RBCuZn-D (Nickel Silver)

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.

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
