Product: Elecxlink Copper Aluminum Welding Rods, 20-Pack 9.8in (25cm) Universal Low Temperature Copper Aluminum Welding Cored Wire for Electric Power, Chemistry
Brand: Elecxlink
Product Specification:  Type: Copper Aluminum Welding Rods  Material: Copper Aluminum  Color: Silver  Diameter: 2mm / 0.08inch  Length: 250mm / 9.84 inches How to use  Step 1: Cleaning and polished the physical surface.  Step 2: Heating the surface of the base material, until the temperature of the base material to the operating temperature of 716--788℉ (380--420 ℃), so you can rely on the base metal heat transfer welding wire to form welds, should not use the flame to burn wire directly, when the surface temperature of the base metal is sufficient, the wire can flow well and penetrate into the metal capillary.  Step 3: When repairing thin aluminum, as long as the base metal heated to the appropriate working temperature, and then use the wire back and forth friction melting to form a weld.  Step 4: Use propane gas to weld small object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding. Package Includes:  20 x 25cm Copper Aluminum Welding Wire. 
NO SOLDER POWDER NEEDED -- There is no need to use other flux powder with aluminum alloy as the welding core and coating as the salt base.
HIGH QUALITY MATERIAL — This low temperature copper aluminum welding rod is made of premium nontoxic, odorless and durable copper and aluminum.
PERFECT WELDING EFFECT -- Designed with full & smooth welding effect because the item comes with internal powder, great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance. Better than normal aluminum welding rod.
APPLICATION -- Include welding filler wire and spray and flame metalizing wire. It also used for argon arc welding and filling material for pure aluminum, connection with aluminum bus and guide rod of electrolytic aluminum plant and electric power, chemistry and so on.
WIDELY USE – This low temperature copper aluminum welding wire is suitable for welding or surfacing welding alloy/ stainless/galvanized steel/ galvanized cast iron/ copper with high strength, good forgeability & good corrosion resistance.
