FLUX COATED LOW FUMING BRONZE

AWS A5.8 RBCuZn-C | ASME SFA5.8 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 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.

Applications:

Used for steel, copper alloys, cast iron, nickel alloys and stainless steel.
