Problems solved by technology

[0002] In the existing technology, aluminum products are made of commercial pure aluminum, which has good processing performance, but relatively weak strength. It is necessary to carry out research on hard aluminum materials, especially for large-scale products, by improving the strength of the material, the shape Strengthening, material consistency control and other methods to promote the purpose of improving the performance of aluminum materials
[0003] The hardness of the commonly used 1070A aluminum is only 18.5HB, the tensile strength is 70MPa, and the yield strength is 34MPa, which has the problem of insufficient strength.
