This type of product is widely used as general welding material with the magnesium of 5% and a little of Titanium fine grains. And this product is of high toughness, good forgeability, and well anti-corrosiveness, Furthermore, it's a good choice for color-match in welding after anodic process.
The model ER5356 do not suggested to use in aluminium alloy workpiece which working temperature is over 65o C, thus will cause corrosion cracking in welded joints. 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. And a plate can be used to hold molten metal to ensure meld form.
The argon arc welding of Aluminium & Magnesium alloy welding wires is used as the filler material, in welding among Al-Mg-Si, Almasilalloy and Aluminium & Magnesium alloy, like: Bicycles, aluminium scoter, etc. Engine carriage, pressure vessel, armory processing, ship-building. Space shuttle, etc.
