Abstract
The invention relates to a high-strength aluminum alloy section bar and a preparation method thereof. The section bar comprises the components of, by weight, 0.4-0.5% of silicon, 1-1.2% of manganese, 2.55-2.75% of zinc, 0.1-0.2% of tantalum, 0.03-0.05% of titanium, 1.22-1.4% of iron, 0.68-1.12% of magnesium, 0.08-0.12% of antimony, 0.08-0.12% of praseodymium, and 0.08-0.12% of thulium. According to the invention, the materials comprise silicon, manganese, and zinc alloy components, such that the strength of the aluminum alloy can be substantially improved. Also, with the added rare earth elements, corrosion resistance and extrusion speed of the alloy are greatly improved. Surface smoothness is improved, and the aluminum section bar is provided with reasonable elongation. Also, a heat treatment process is improved, such that aluminum alloy section bar strength hardness, wear resistance, and elongation rate are improved. According to testing, the yield strength reaches 280MPa, a tensile strength reaches 324MPa, and an elongation rate is 13%.
Description
technical field [0001] The invention belongs to the technical field of aluminum alloys, in particular to a high-strength aluminum alloy profile and a preparation method thereof. Background technique [0002] my country is a big producer of aluminum profiles, and architectural aluminum profiles account for the vast majority of the entire aluminum profile market, but they often provide low-end products, mainly used for building doors and windows, indoor and outdoor decoration, and curtain wall structures with low requirements. The existing aluminum alloy profiles have poor strength performance, and after being used as building doors and windows for a period of time, they are prone to distortion or deformation, which affects the appearance. Contents of the invention [0003] The object of the present invention is to provide an aluminum alloy profile with high strength and high hardness and a preparation method thereof. [0004] Technical scheme of the present invention is as...
