RBCuZn-D 1/8″ Nickel Silver Bare 10 lb Box Brazing Rods Welding Wire Blue Demon
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 AWS Specification AWS A5.8/A5.8M:2011 AWS Classification RBCuZn-D Typical Wire Chemistry Al 0.01 Ni 9.0 – 11.0 Pb 0.05 P 0.25 Si 0.04 – 0.25 Cu 46.0 – 50.0 OTHER 0.50 Zn REM Typical Physical & Mechanical Properties Melting point 1680ºF Solidification 1665ºF Tensile Strength, ksi 70 Elongation%, min 25 Brinell Hardness 120 Brazing Positions H,V Available Diameters 1/16″, 3/32″, 1/8″, 5/32″, 3/16″ & 1/4″
