This braze welding rod are similar to RBCuZn-A rods but contain additions of iron and manganese which serve to increase the hardness and strength. In addition, a small amount of silicon serves to control the vaporization of the zinc, yielding the low-fuming" property. The nickel addition assures uniform distribution of the iron in the deposit.
Special performance
Low fog properties, zinc evaporation is controlled by the addition of silicon
Stable arc, small splash, uniform slag covering, easy slag removal, good weld forming
The metal has good strength, plasticity, toughness and porosity resistance
