Anti-rust aluminum sheet material properties and advantages

Edit:admin001 Date: 2019-05-22 16:02
The rustproof aluminum plate is mainly an Al-Mn system and an Al-Mg alloy. Because the effect of strengthening the aging 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 excellent corrosion resistance, so it is called rust-proof aluminum plate.
Aluminum-magnesium alloys and aluminum-manganese alloys are collectively referred to as rust-proof aluminum, because the alloy composition between the two increases their anti-corrosion properties. The representative of aluminum-manganese alloys is 3003, 3004, 3105. The first one is widely used, the second one is generally It is used on the top of the can, the latter is the wire and other upper ones with higher conductivity requirements. The aluminum-magnesium alloy is used according to the content of magnesium alloy, which is 5005 5252 5251 5050 5052 5754 5083 5056 5086, etc. Some anti-corrosion properties include industries with high strength requirements, such as shipbuilding, containers and subway high-speed trains.
A pressure-processable aluminum alloy with good corrosion resistance in media such as atmosphere, water and oil. It mainly includes Al-Mn-based and Al-Mg-based alloys which cannot be heat-treated and strengthened. The rust-proof aluminum alloy containing 1.0% to 1.7% of manganese has high corrosion resistance. The magnesium content of the Al-Mg rust-proof aluminum alloy generally does not exceed 7%. As the magnesium content increases, the strength of the alloy increases, σ0 can reach 400 MPa, and the plasticity decreases. This type of rust-proof aluminum alloy is usually used in an annealed state, cold hardened or semi-cold hardened state. Low strength, good plasticity, easy pressure processing, good corrosion resistance and weldability are particularly suitable for the manufacture of deep drawn parts subjected to low loads, welded parts and parts working in corrosive media, such as fuel tanks and pipes. Another type of rust-proof aluminum alloy is a heat-treatable Al-Zn-Mg-Cu alloy with high tensile strength, excellent seawater corrosion resistance, good fracture toughness, low notch sensitivity and good Molding process performance. Suitable for the manufacture of seaplane skins and other high-strength sheet metal parts that require corrosion resistance.
The rust-proof aluminum 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 action of manganese, and have good weldability and plasticity, but have poor cutting properties. The Al-Mg alloy has a higher density than pure aluminum than the Al-Mn alloy due to the action of magnesium, and has a relatively good corrosion resistance. The aging effect of the rust-proof aluminum alloy is extremely weak and can only be hardened by cold deformation, but the plasticity is significantly reduced.
