The corrosion resistance of aluminum coil is very good, which is close to that of industrial pure aluminum. It has good corrosion resistance to atmosphere, fresh water, seawater, food, organic acid, gasoline, neutral inorganic saline solution, etc. and it also has good corrosion resistance in dilute acid. In the cold deformation state, the aluminum coil has the tendency of spalling corrosion. The larger the deformation is, the more serious the spalling is. Due to the uneven color after anodizing, anodizing treatment is generally not carried out.
5052 aluminum coil has good forming and processing performance and corrosion resistance. It is the most widely used antirust aluminum. The products are widely used in the fields of pull rod box, oil tank material, liquid crystal back plate, tank material, door plate material and so on.
The product process of 5083 aluminum coil, through the determination of alloy composition, optimization of melting and casting process, homogenization heat treatment and rolling process test, the product performance is equivalent to that of foreign materials, meets the requirements of users, especially meets the increasing processing needs of complex parts such as marine aluminum plate, rail transit, automobile and mold, and has a very broad application prospect.
5182 aluminum coil is widely used. 5182 aluminum alloy has good corrosion resistance, excellent weldability, good cold workability and medium strength. It is widely used in automobile lightweight aluminum.
5754 aluminum coil products have excellent corrosion resistance, excellent processing performance, weldability and easy processing and forming. 5754 aluminum alloy plates in different heat treatment states are the main materials used in automobile manufacturing industry (car door, mold and seal) and can making industry.
