XTRweld LFB (Low Fuming Bronze), also known as RBCuZn-C, is a general-purpose copper-based alloy brazing rod used for oxyacetylene welding and brazing a variety of ferrous and nonferrous metals. It’s ideal for joining carbon steel, copper alloys, cast iron, stainless steel, malleable iron, and some nickel alloys. Display Pack: 1 lb. With excellent ductility, machinability, and low fume generation, LFB is a must-have in any welding shop. The flux-coated (White) version eliminates the need for external flux, while the bare version should be used with a borax-boric acid-based brazing flux for optimal performance.

• Suitable for brazing steel, copper alloys, stainless, cast iron, and more
• Produces clean, strong joints with minimal spatter and low fuming
• Great for sheet metal work and high-strength repairs
• Excellent mechanical properties with good tensile strength and elongation
