No Need Solder Powder: You don’t need to use other powder flux with aluminum alloy as welding core and coating as salt base. Application : this kind of low temperature aluminum welding wire can weld almost all white metal, including aluminum, aluminum alloy, cast aluminum, aluminum magnesium alloy and so immediately. Effect: with full and smooth welding effect thanks to the internal powder. With low melting point, great solderability and corrosion resistance, high thermal conductivity, high electrical conductivity and excellent processing performance. Instructions: Step 1 : Polish the surface by physical cleaning. Step 2: Heat the surface of the base metal until the temperature reaches the solder wire working temperature of 450°C or more, so that the weld can be formed by the base metal thermal conduction welding wire, and the flame welding wire should not be used, and only when the surface temperature is sufficient, the wire can flow and penetrate well. Step 3: When repairing
