Description

technical field [0001] The invention belongs to the field of alloys, in particular to a high ductility aluminum alloy material. Background technique [0002] The density of pure aluminum is small (ρ=2.7g / cm 3 ), which is about 1 / 3 of iron, with a low melting point (660°C). Aluminum has a face-centered cubic structure, so it has high plasticity and is easy to process, and can be made into various profiles and plates. Aluminum has good corrosion resistance; however, the strength of pure aluminum is very low, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people have gradually strengthened aluminum by adding alloying elements and using heat treatment, which resulted in a series of aluminum alloys. The aluminum alloy formed by adding certain elements can also have high strength while maintaining the advantages of pure aluminum such as light weight, σ b Values ​​up to 24 ~ 60kgf / mm 2 . This makes the aluminum...
