RBCuZn-B Welding Wire
1. Physical And Mechanical Properties
(1). Solidus: 866℃
(2). Liquidus: 882 ℃
(3). Denseness: 8.39kg/dm³
2. Application
RBCuZn-B welding wire contains a small amount of iron, silicon, manganese brass wire. The molten metal has good fluidity, and the evaporation of zinc is more effectively suppressed due to the presence of silicon. It can be used for argon arc welding of molten metal in copper, steel, copper-nickel alloy, gray cast iron, and inlaid carbide tools. Preheating at 400-500 °C before welding.
