5083 aluminum plate belongs to Al-Mg alloy, widely used, especially in the construction industry cannot do without this alloy, is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, and moderate strength. Through alloy composition determination, casting process optimization, homogenizing heat treatment and rolling process test, the product performance is comparable to that of foreign materials, especially to meet the processing needs of Marine aluminum plate, rail transit, automobile, mold and other complex parts, and the application prospect is broad.
