SÜA - RBCuZn-C - Low-Fuming Bronze Brazing Rod - Flux Coated - 18 x 1/16 - (1/2 Lb - 24 Rods)

Recommended Braze-Welding Procedure: Preheating is recommended for some applications however overheating should be avoided. Voids may be formed in the joint by entrapped zinc vapors. Bevel cracks or heavy sections. Clean the area to be brazewelded as thoroughly as possible. Joint clearances of 0.002” – 0.005” (0.05 – 0.13mm) are suitable. Using a slightly oxidizing flame preheat the part to be brazed. If using LFB dip the rod into the bronze brazing flux (there is no need for more flux if using LFBFC) and then back to the area being brazed while keeping the torch in constant motion to avoid overheating. The molten drops of LFB or LFBFC will follow the heat of the torch flame. Repeat the process until the joint is filled (Note: A benefit to using LFBFC over LFB isthat it is not necessary to remove flux residue between passes). Allow the part to cool slowly before removing any slag then use a wire brush to bring out a nice yellow brass color.
