Washington Alloy Bronze is a 1% tin filler metal used for brazing or oxyacetylene welding of steel, cast iron, malleable iron, copper-bronze, and nickel alloys. The addition of tin improves strength and corrosion resistance in the weld deposit. Borax-boric acid flux is generally required. Joint clearances should be 0.002” to 0.005” wide. Preheating may be desirable for some applications. Neutral or slightly oxidizing flames should be used.
