3003 marine grade aluminum plate is a common series of aluminum-manganese alloy products. Superior to having a manganese alloy element, this product has excellent anti-rust properties, also known as rust-proof aluminum. The strength of about 1100% higher than 1100, formability, weldability, corrosion resistance are good.
3003 marine grade aluminum sheet features: 3003 is AL-Mn series alloy, which is the most widely used type of rust-proof aluminum. Its strength is not high (slightly higher than that of industrial pure aluminum) and can not be strengthened by heat treatment. Therefore, the cold working method is adopted to improve its mechanical properties: In the annealed state has a high plasticity, plasticity is still good in the semi-cold hardening, cold work hardening low plasticity, corrosion resistance, good weldability. 3003 marine grade aluminum plate commonly used in ships, ships, vehicle materials, automotive and aircraft plate welding parts. 3003 marine grade aluminum sheet chemical composition:
Al: balance, Si: 0.6, Cu: 0.05-0.2, Zn: 0.10, Mn: 1.0-1.5, Fe: 0.7.
3003 marine grade aluminum plate mechanical properties:
Tensile strength σb (MPa)) 120-160 Conditional yield strength σ0.2 (MPa)) ≥85 [3]
