5183 aluminum wire for mig welder is a magnesium close to 5% and higher manganese content of aluminum magnesium welding wire, with good corrosion resistance, high strength, heat resistance, good ductility. After the welding of the welding seam is still white, it can provide a good color for the welded joints. For some of the alloys, the strength of the welded joints is slightly higher than 5356 aluminum wire for mig welder.  
Application:
used as a filler metal for argon arc welding of aluminum magnesium (3%Mg) alloy, which is used in the locomotive, nuclear industry, shipbuilding, chemical pressure vessel, refrigeration, boiler and aerospace industry.

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.
