5083 is a high magnesium alloy high-precision super flat plate, thickness tolerance within plus or minus 0.05, plate flatness of a square within 10 silk, 5083 characteristics of the processing of non-deformation, in the non-heat-treatable alloys with good strength, good corrosion resistance, good machinability. Beautiful surface after anodizing treatment. Arc welding performance is good.
The main alloying element in alloy 5083 is magnesium, which provides good corrosion resistance and weldability, as well as moderate strength. Excellent corrosion resistance makes 5083 alloy widely used in marine applications such as ships, as well as automobiles, aircraft weldments, subways, light rail, pressure vessels requiring strict fire protection (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration units, television towers, drilling equipment, transportation equipment, parts, armor and so on.
5083 belongs to the Al-Mg-Si system alloy, the use of a wide range, especially the construction industry can not do without this alloy, is a promising alloy. It has good corrosion resistance, excellent weldability, good cold workability, and medium strength. 5083's main alloying element is magnesium, which has good forming and processing performance, corrosion resistance, weldability, and medium strength. At the same time 5083 also belongs to the AL-Mn system alloy, is widely used a kind of rust-proof aluminum, this alloy has high strength, especially with fatigue strength: plasticity and corrosion resistance is high, can not be heat-treated to strengthen,, in the semi-cold-worked hardening of plasticity is still good, cold-worked hardening of plasticity is low, corrosion resistance is good, weldability is good, machinability is poor, and can be polished.
