LOW FUMING BRONZE ALLOY

 

AWS A5.8 Class RBCuZn-C

Washington Alloy Low Fuming Bronze is a general-purpose oxyacetylene brazing rod used for steel, copper alloys, cast iron, nickel alloys, and stainless steel. A balanced chemical analysis of copper and zinc, as well as alloying elements of tin, iron, manganese, and silicon, produce weld deposits that are easily attained simply by applying a neutral or slightly oxidizing flame. The high silicon content of Washington Alloy Low Fuming Bronze keeps fumes to a minimum. Preheating is required for some applications and bronze brazing flux is required for the bare rods.
