LFB Silicon Bronze Brazing/Bronze Welding Rods – 5 pcs 1.6 x 300mm

£2.70

You are buying 5 x 300mm lengths of LFB (Low Fuming Bronze) SILICON BRONZE BRAZING/TIG WELDING RODS. Ideal for Classic Car Bodywork Repairs. This Low Fuming Bronze (LFB) and Flux-Coated Bronze (LFBFC) are general purpose oxyacetylene rods for braze welding steel, cast iron, malleable iron and some nickel alloys. Commonly used for fusion welding of brass, bronze and copper alloys as well as for building up wearing surfaces. LFB and LFBFC are excellent choices for rush jobs or temporary applications involving dissimilar metals or where rust is present. Galvanized parts can be brazed without causing damage to the zinc coating. A precisely formulated chemical balance of copper and zinc as well as alloying elements of tin, iron and manganese produce high strength, ductile and sound weld deposits that can be easily machined and work harden once put into service. The high silicon content keeps fumes to a minimum and allows for good tinning action. Preheating is recommended for some applications and bronze brazing flux is required for the bare rods. Use a slightly oxidizing flame for braze-welding and build up applications and a neutral flame for fusion welding. Excellent color matches on yellow brass and bronze castings. The optimum joint gap for brazing is normally 0.05-0.2mm. Composition (%): Cu: 56.0-60.0;  Zn: Balance;   Fe: 0.25-1.20;  Si: 0.04-0.15;  Al: 0.01 max;  Pb: 0.05 max; 0.01-0.50; Mn: 0 Sn: .80-1.10;   Total Other(s):  0.50. Conforms to: EN 1044 1999 CU302, AWS A5.8 RB Cu Zn A. Melting range: 888°C. LARGER BATCHES AVAILABLE UPON REQUEST
