Summary of the advantages and characteristics of 3003 Aluminium Sheet
04-20
3003 Aluminium Sheet is mainly Al-Mn and Al-Mg alloys. Because the aging strengthening effect is not obvious, it is not suitable for heat treatment strengthening, but the strength and hardness can be improved by work hardening. The main performance characteristics of this type of alloy are medium strength, good plasticity and corrosion resistance, so it is called anti-rust aluminum, and it has good weldability. It is an aluminum alloy widely used in welded structures.
Advantages of 3003 Aluminium Sheet
Aluminum-magnesium alloy, 3003 Aluminium Sheet and aluminum-manganese alloy are collectively referred to as anti-rust aluminum because the alloy components between the two increase their anti-corrosion performance. The two are generally used on the can body, the latter is used on wires and other high conductivity requirements. According to the content of magnesium alloy, the order of aluminum-magnesium alloy is: 5005 5252 5251 5050 5052 5754 5083 5056 5086, etc. , respectively used in some industries with high anti-corrosion performance and high strength requirements, such as shipbuilding, containers and subway high-speed trains. Press-processable aluminum alloys with good corrosion resistance in atmospheric, water and oil media.
It mainly includes Al-Mn and Al-Mg alloys that cannot be strengthened by heat treatment. The anti-rust aluminum alloy with manganese content of 1.0% to 1.7% has high corrosion resistance. The magnesium content in the Al-Mg anti-rust aluminum alloy generally does not exceed 7%. With the increase of the magnesium content, the strength of the alloy increases, σ0 can reach 400MPa, while the plasticity decreases. This type of rust-resistant aluminum alloy is usually used in the annealed, work-hardened or semi-cold-hardened state. Low strength, good plasticity, easy pressure processing, good corrosion resistance and welding performance, especially suitable for the manufacture of low-load deep-drawn parts, welded parts and parts that work in corrosive media, such as fuel tanks, pipelines, etc.
Another type of rust-proof aluminum alloy is the heat-treatable Al-Zn-Mg-Cu alloy, which has high tensile strength, excellent seawater corrosion resistance, good fracture toughness, low notch sensitivity and good corrosion resistance. Forming process performance. Suitable for manufacturing seaplane skins and other high-strength sheet metal parts that require corrosion resistance. 3003 Aluminium Sheet mainly contains alloying elements such as manganese and magnesium. Ai-Mn alloys have higher corrosion resistance and strength than pure aluminum due to the effect of manganese, and have good weldability and plasticity, but poor cutting performance. Due to the effect of magnesium, Al-Mg alloys have lower density than pure aluminum and higher strength than Al-Mn alloys, and have quite good corrosion resistance.
