Description

technical field [0001] The invention belongs to the technical field of metal materials, in particular to a novel aluminum alloy material and a preparation method thereof. Background technique [0002] Aluminum is the metal element with the highest content in the earth's crust. It has relatively high strength and good plasticity. It can be processed into various profiles and has good electrical conductivity, thermal conductivity and corrosion resistance. In some fields, the use of aluminum alloys instead of iron alloys can reduce self-weight to reduce energy consumption and environmental pollution, and is of great significance in saving limited resources. [0003] However, aluminum alloys have certain defects in use, which affect the application range of aluminum alloys. The most important thing is that the strength of aluminum alloys is lower than that of iron alloys, and their ductility, shock resistance and toughness are insufficient. [0004] In the prior art, in order t...
