Can Aluminum Plates be Rustproof?

Anti-rust materials have always been favored by all walks of life, today to introduce you to the anti-rust star in the aluminum alloy material——3003 aluminum alloy. Anti-rust materials have always been favored by all walks of life, today to introduce you to the anti-rust star in the aluminum alloy material - 3003 aluminum alloy.

3003 aluminum alloy belongs to AL-Mn alloy. It is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum), and it can not be heat-treated. Therefore, cold working method is used to improve its mechanics. Performance: It has high plasticity in the annealed state, good plasticity in semi-cold hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. 3003 aluminum alloy has good corrosion resistance, close to the corrosion resistance of industrial pure aluminum, and has good corrosion resistance to atmospheric, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc. The corrosion resistance is also very good. In the cold deformation state, the 3003 aluminum alloy has a tendency to peel off and corrode, and the larger the deformation, the more severe the peeling. Since the color is not uniform after anodization, the anodization is generally not performed.

3003 aluminum alloy chemical composition

Manganese Mn: 1.0 to 1.5, copper Cu: 0.05 to 0.2, iron Fe: 0.7, silicon Si: 0.60, zinc Zn: 0.10, aluminum Al: balance

3003 alloy aluminum plate use

Applications are mainly for low-load parts that require high plasticity and good weldability, working in liquid or gaseous media, such as fuel tanks, gasoline or lube oil pipes, various liquid containers and other small-load parts made with deep drawing. The wire is used to make rivets.
