These SÜA rods have the alloy and rod diameter printed on the coat for easier identification. Voids may be formed in the joint by entrapped zinc vapors. Mechanical and physical characteristics include ductility, machineability, high strength, free flowing with good tinning action and a low melting point (1630°F) Repeat the process until the joint is filled (Note: A benefit to using LFBFC over LFB is that it is not neces ary to remove flux residue between passes). RBCuZn-C (Low Fuming Bronze Bare And Flux Coated) - Welding Material Sales Rod Length: 18 for easier maneuverability while welding since flux coated rods cannot be bend. 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. Allow the part to cool slowly before removing any slag, then use a wire brush to bring out a nice yellow brass color. Recommended Braze-Welding Procedure: Preheating is recommended for some applications, however, overheating should be avoided. Please check Picture #2 for an approximate quantity of rods per pound*** The molten drops of LFB or LFBFC will follow the heat of the torch flame. Lincoln Electric 1/8 in. Flux-Coated Brazing Rods (1 lb. Tube) KH515 Available in different package weights: 1/2 Lb, 1 Lb, 2 Lb, and 5 Lb - Choose rod diameter and package quantity from the menu. Available in different sizes: 1/16, 3/32and 1/8. LFBF (Fluxcoated low fuming bronze) is a general purpose oxyacetylene/brazing rod used for joining various ferrous and non-ferrous metals such as carbon steel, copper alloys, cast iron, malleable iron, stainless steel and some nickel alloys. 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 cons ant motion to avoid overheating.
