Description

【Technical field】 [0001] The invention belongs to the technical field of aluminum alloy material preparation, and in particular relates to a preparation process of an aluminum alloy material with good oxidation resistance. 【Background technique】 [0002] Aluminum alloy is an extended product of pure aluminum. The density of pure aluminum is small (ρ=2.7g / m3), about 1 / 3 of that of iron, and its melting point is low, about 660°C. Aluminum has a face-centered cubic structure, so it has High plasticity (δ: 32-40%, ψ: 70-90%), so it is easy to process, can be made into various profiles and plates, and 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 alloy formed by adding certain elemen...
