ER1070
Performance: ER1070 Pure aluminum welding wire containing more than 99.7% aluminum, it has advantages rang over good anti-corrosiveness, well heat and electronic conductivity, machinability, low strength. And it also is kind of best choice for color-match after anodic process.
You should strictly clean the oxide film on the edge of the workpiece and oil before welding, otherwise it will make bad weld produce and cause porosity, slag inclusion and other defects.
You can use a plate to hold molten metal to ensure meld form and avoid cracks.
Usage: The argon arc welding of pure aluminum is used as the filler material, widely used in electrolytic aluminum bus bar and rod connections and ships, railway locomotive, chemical, food, sports equipment, electric power, etc.
