Brass welding rod is a special brass wire with a small amount of tin and silicon. It is a kind of universal welding material with wide application. Features: It can weld copper, steel, and hard alloy materials at temperatures ranging from 890℃ to 905℃. Containing a small amount of tin and silicon, tin can improve the fluidity of the wire, and silicon can effectively control the evaporation of zinc. Good mechanical properties, good wear resistance, excellent fluidity, suitable for temperatureless cold welding. No Need Solder Powder - You don't have to use other flux powder with brass as the welding core and coating as the salt base. Very convenient and easy to weld. Light weight, small volume, very easy to carry. Specification: Main material: brass Color: golden Melting point: 890℃～905℃ Quantity: 10pcs / 20pcs / 50pcs (optional) Diameter: 1.6mm / 0.06in Length: 250mm / 9.8in Package size: 10pcs: 250 * 7 * 7mm / 9.8 * 0.3 * 0.3in 20pcs: 250 * 9 * 9mm / 9.8 * 0.4 * 0.4in 50pcs: 250 * 30 * 30mm / 9.8 * 1.2 * 1.2in Package weight: 10pcs: 43g / 1.5oz 20pcs: 86g / 3.0oz 50pcs: 215g / 7.6oz Note: 1. The weld bevel and the wire surface must be carefully cleaned before welding. 2. Preheating to 400-500℃ before welding. Copper gas welding solvent must be used as a solvent during welding. 3. The welding flame should adopt neutral flame or slight oxidation flame, appropriately reducing the temperature during welding, increasing the welding speed, minimizing the residence time of the molten pool at high temperature, and then can reduce the evaporation and oxidation of zinc.
