Antirust aluminum sheet plate mainly includes aluminum-magnesium alloy, and aluminum-manganese alloy, because the alloy components in the middle of both have increased their anti-corrosion properties, this type of alloy can not be heat-treated to strengthen, so the strength is low.
The main performance characteristic of these alloys is excellent corrosion resistance, so it is called rust-proof aluminum.
It has high plasticity, low strength, excellent corrosion resistance and welding performance, easy processing and molding, and has good gloss and low temperature performance, suitable for manufacturing parts with little force working in corrosive environment, and is the most widely used aluminum alloy in welding structure.
It is the most widely used aluminum alloy in welded structures. The rustproof aluminum plate that cannot be strengthened by heat treatment is mainly hardened by processing to improve its strength and hardness. After work hardening, different annealing temperatures are used to achieve the required strength and plasticity to meet different usage requirements.
Aluminum manganese alloy is represented by 3105, 3004, 3003 aluminum alloy, the first kind of electric wire and other high conductivity requirements above the use. The second one is generally used on the top of cans, and the last one is widely used, such as kitchenware, food and chemical products handling and storage devices, tanks and cans for transporting liquid products, and various pressure vessels and pipes processed by thin plates.
According to the magnesium content of aluminum and magnesium alloy in order: 5005, 5252, 5251, 5050, 5052 aluminum alloy and so on, respectively, used in some anti-corrosion performance and strength requirements of higher industries, such as shipbuilding, containers and subway high-speed trains. It is a pressure processable aluminum alloy with good corrosion resistance in the medium of atmosphere, water and oil.
