The invention belongs to the technical field of composite material, and particularly relates to an aluminum alloy and a machining method thereof. The aluminum alloy is composed of, by weight, 92%-96%of aluminum (AL), 1.5%-2% of lithium (Li), 0.8%-1.2% of cobalt (Co), 1%-2% of nickel (Ni), 2%-2.5% of iron (Fe) and 0.2%-0.5% of manganese (Mn); raw materials further comprise rare earth metal powderaccounting for 2%-5% of the total mass; the rare earth metal powder is powder obtained by crushing and grinding metals mixed by lanthanum (La), cerium (Ce) and gadolinium (Gd) according to the proportion of 1:1:1; the particle size of the rare earth metal powder is between 10 micrometers and 20 micrometers; and carbon fibers are PAN-based carbon fibers. According to the aluminum alloy and the machining method thereof, the shape of an aluminum alloy product before forming and after pre-forming can be achieved, manpower and material resource waste in the grinding and cutting process after aluminum alloy product forming can be effectively avoided, the phenomena that in the aluminum alloy product forming process, wrinkles are generated, and components in the aluminum alloy are distributed unevenly can be effectively avoided, and then the purpose of improving the overall quality of the aluminum alloy product is achieved.
Description
technical field [0001] The invention belongs to the technical field of composite materials, in particular to an aluminum alloy and a processing method thereof. Background technique [0002] With the development of technology, the existing aluminum alloys are more and more widely used in the field of making shells, especially in the application field of smart device shells. Aluminum alloys are made with light texture, excellent ductility and moldability. It is widely used, but in the existing technology, the shell made of aluminum alloy has the above advantages, but also has the disadvantages of poor strength, not hard enough, easy to deform, etc. For details, please refer to the journal Metal and Powder Metallurgy, New Material Industry, 2019 (12). [0003] An aluminum alloy material released by a Chinese patent, patent number 201810272188, includes: 10% to 15% copper; 0.15% to 0.3% manganese; the balance is aluminum; the solution adjusts the metal elements added to the alu...
