5356 aluminum wire for mig welder is a magnesium alloy with magnesium 5% and a small amount of titanium refined aluminum alloy welding wire, with good corrosion resistance, high strength,  high heat resistance,good ductility. Weld anodizing treatment is still white, can provide a good match for welded joints, is a widely used general consumables.  
Application:
aluminum magnesium (3%Mg) alloy argon arc welding of the most basic metal filler metal, in the aluminum silicon magnesium, aluminum magnesium alloy welding and aluminum magnesium alloy castings were also used in welding. Such as the carriages,  bicycles,chemical pressure vessel, aluminum plate and other sports equipment and ordnance pwireuction, shipbuilding, aviation and other industries.

Note: 
1. Because of the stress corrosion cracking of the welded joint of aluminum alloy when the temperature is above 65 degrees, the electrode is not used in the structure of aluminum alloy in such a temperature environment.
 
2. Welding should be strict and clear the edge of the welding of the oxide film and oil, otherwise it will cause welding seam welding and cause the hole, slag and other defects.
 
3. Welding can be used for holding molten metal plate, in order to ensure the weld forming, and avoid hot crack.
