Rust resistant aluminum alloy refers to a pressure processable aluminum alloy that has good corrosion resistance in media such as atmosphere, water, and oil.
The aging hardness effect of rust resistant aluminum alloy is extremely weak, and can only be hardened by cold deformation, but it will significantly reduce plasticity. Depending on the type and content of metal elements contained in the alloy, it will have different properties.
Al+Zn+Mg structured aluminum alloy. It has high strength (equivalent to LY12), good fracture toughness, high plasticity, low sensitivity to cylinder mouth, excellent resistance to seawater and marine atmospheric corrosion, no tendency towards intergranular corrosion, peeling corrosion, and stress corrosion, and good weldability.
Al Mg alloys with lower magnesium content cannot be strengthened by heat treatment, have low strength and high plasticity. Cold deformation can strengthen the alloy, but reduce plasticity. Good corrosion resistance and weldability, suitable for working in marine atmospheres. Can manufacture lightweight components such as aviation fuel tanks, oil pipes, brackets, etc. that require high process plasticity and corrosion resistance.
Al Mg alloys with moderate magnesium content cannot be heat treated for strengthening. Low strength, high plasticity, and cold deformation can improve strength. Good weldability and excellent corrosion resistance. Suitable for manufacturing components such as pipes, containers, skeletons, etc. that require high process plasticity and corrosion resistance under moderate loads.
Al Mg alloys with high magnesium content cannot be heat treated for strengthening. Low strength, good plasticity, good weldability, and corrosion resistance. Suitable for manufacturing parts such as medium load welded pipelines and liquid containers that require high plasticity and corrosion resistance.
