3003 anti-rust aluminum plate: mainly Al-Mn series and Al-Mg series 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 rust-proof aluminum and has good weldability. It is an aluminum alloy widely used in welded structures.
Aluminum-magnesium alloy, 3003 aluminum plate and aluminum-manganese alloy are collectively referred to as rust-proof aluminum because the alloy components between the two increase their anti-corrosion performance. The first one is generally used on the can body, the latter one 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., They are 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 rust-proof 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. It is suitable for the manufacture of seaplane skins and other high-strength sheet metal parts that require corrosion resistance. The 3003 anti-rust aluminum plate alloy 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.
The aging hardness effect of rust-proof aluminum alloy is extremely weak, and the 3003 aluminum plate can only be hardened by cold deformation, but the plasticity will be significantly reduced.
AL-Mn alloy is a widely used anti-rust aluminum. This alloy has high strength, especially fatigue resistance: high plasticity and corrosion resistance, cannot be strengthened by heat treatment, and has good plasticity during semi-cold work hardening. Low plasticity during cold work hardening, good corrosion resistance, good weldability, poor machinability, and polishable.
The 3003 anti-rust aluminum coil has high aluminum content and smooth surface. The edge of the 3003 aluminum plate can be chamfered, which is better than the gj standard. The 3003 anti-rust aluminum coil has high aluminum content, and the electrical conductivity and thermal conductivity of aluminum are only Conventional metal lower than copper. The resistivity of 3003 anti-rust aluminum coil is very small. 3003 anti-rust aluminum coil is mainly used for anti-corrosion covering leather, and is also suitable for heat exchanger fins. Aluminum alloy 3003 anti-rust Aluminum coil is one of the alloys with high strength and good resistance to stress corrosion cracking. It is suitable for thick plates, forged aircraft, high-speed rotary bodies, and alloys for welding structures. the strength of the material.
