3003 aluminum sheet belongs to Al-Mn alloy, which is the most widely used anti-rust aluminum. How about the 3003 aluminum properties? Its strength is not high and it cannot be strengthened by heat treatment, so cold working method is used to improve its mechanical properties.
3003 Aluminum has high plasticity in the annealed temper, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. Its common tempers are H12, H22, H14, H18, H24, H26, H112, etc.
The H temper is the common temper of the finished aluminum sheet, which means that the aluminum sheet has undergone work hardening treatment to improve the strength. Among the 5 basic states of aluminum plates (F, O, H, W, T), the H state is the state we most often come into contact with and has the most subdivision states.
3003 H14 aluminum sheet
3003 h14 aluminum sheet has good processability and can be deep drawn, spun, welded or brazed. This aluminum sheet is widely used for fairing and baffle plating. The ultimate strength is 21000 PSI and the shear strength is 14000 PSI.
3003 H18 aluminum sheet
3003 H18 aluminum plate belongs to the aluminum plate that has not been processed after rolling and cold rolling, so it belongs to the aluminum plate that is not quenched and processed. It has a relatively short delivery short.
3003 H24 aluminum sheet
3003 H24 aluminum plate occupies 80% of the production of 3003 aluminum sheet. After annealing process, 3003 H24 aluminum plate can be bent at 90 degrees without cracking. Therefore, 3003 H24 aluminum plate is widely used.
3003-O aluminum plate
The production and processing steps of 3003-O aluminum sheet are similar to the production process of 3003 H24 aluminum plate. However, the quenching time of the 3003-O aluminum plate is long, and the production process is also relatively long. It is more suitable for stamping molds because it is softer.
