Low Temperature Aluminum Electrodes Do Not Require Solder Powder For Soldering Great Welding Effect - With full & smooth welding effect because of internal powder. With low melting point(647658), great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance. Very Wide Application It is mainly used for argon arc welding and filling material for pure aluminum, connection with aluminium bus and guide rod of electrolytic aluminium plant and electric power, chemistry, food and so on. No Need Solder Powder You don't have to use other flux powder with aluminum alloy as the welding core and coating as the salt base. Very convenient and easy to weld. Widely Use In Life Suitable for welding or surfacing welding alloy with high strength, good forgeability & good corrosion resistance. Light Weight & Small Volume Size of 500X2mm & weight of 4g, very easy to bend & carry. Storage: placed in a ventilated and dry place, can be stored for a long time Size: 50 X 0.2cm Quantity: 20CS Material: Aluminum Color: Silver Melting Point: 647658 Diameter: 2mm / 0.078" Length: 500mm / 19.7" Recommended for welding or brazing aluminum alloy: 1060, 1350, 3003, 3004, 3005, 5005, 5050, 6053, 6061, 6951, 7005, and cast alloys 710.0 and 711.0 Item Wight: Approx. 4g How to Use: Step 1: Clean and polishe the physical surface. Step 2: Heat the surface of the base material, until the temperature of the wire to the operating temperature of 380400, so you can rely on the parent metal heat transfer welding wire to form welds, should not use the flame to burn wire. Step 3: When repairing thin aluminum, as long as the aluminum base metal heated to the appropriate working temperature, and then use the wire back and forth friction melting to form a weld, only with a metal brush melt welding wire to weld at the weld. Step 4: Use propane gas to weld s mall object, natural slow cooling after welding. NOTE: 1. The surface of the base metal must be clean. 2. The base metal temperature to reach 400 degrees, including the process of welding the base metal temperature should be maintained at 400, and the temperature can be high or low. Package Include: 20PCS Low temperature aluminum wire core.
