Description

technical field [0001] The invention belongs to the technical field of aluminum alloy materials, in particular to a pressure-resistant aluminum alloy material and a preparation method thereof, and also to a preparation method of the aluminum alloy material. Background technique [0002] Aluminum has low density and low melting point, but aluminum has a face-centered cubic structure, so it has high plasticity and is easy to process. It can be made into various profiles and plates, and has good corrosion resistance. However, the strength of pure aluminum is very low, and it is in an annealed state, so it is not suitable for structural materials; [0003] However, aluminum alloys have been produced, and zinc alloys are the most widely used class of non-ferrous structural materials in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for...
