Flux-Coated Low Fuming Bronze Brazing Rod – RBCuZn-C, , 1 lb Pack (Select Size From Options Above)

General-purpose 18" or 36" flux-coated bronze brazing rod for steel, cast iron, stainless steel, copper alloys, and nickel alloys.
Washington Alloy Flux-Coated Low Fuming Bronze is an AWS A5.8 RBCuZn-C oxyacetylene brazing rod designed for a wide range of repair, fabrication, and maintenance applications. Its copper-zinc alloy composition includes tin, iron, manganese, and silicon to provide dependable brazing performance with a neutral or slightly oxidizing flame.

The high silicon content helps keep fumes to a minimum, while the factory-applied flux coating makes the rod convenient for brazing applications where a separate flux would otherwise be required.

Package Information: This Arc-Zone listing is sold in 1 lb packs. Each brazing rod is either 18" or 36" long and available in 1/16" or 3/32" diameter.
