Abstract

The invention relates to the technical field of deep machining of aluminum alloy materials, in particular to an aluminum profile with high plasticity and strong compression resistance and a preparation process of the aluminum profile. The aluminum profile with high plasticity and strong compression resistance is prepared from, by weight, 0.4%-0.8% of silicon, 0.4%-0.6% of iron, 0.05-0.15% of lanthanum, 0.05-0.15% of neodymium, 0.35%-0.8% of magnesium, 0.02%-0.04% of manganese, 0.04%-0.08% of zinc and the balance aluminum. According to the prepared aluminum profile with high plasticity and strong compression resistance, since lanthanum and neodymium are added and cooperated with iron, magnesium, manganese and zinc, the prepared aluminum profile has excellent plasticity, compression resistance and pulling resistance, wherein the pulling resistance can reach 240MPa or more, and yield reaches 220MPa or more. The preparation process of the aluminum profile with high plasticity and strong compression resistance is simple in method, low in production cost and applicable to large-scale production.

Description

technical field [0001] The invention relates to the technical field of deep processing of aluminum alloy materials, in particular to an aluminum profile with high plasticity and strong compression resistance and a preparation process thereof. Background technique [0002] Aluminum profiles are products made of aluminum and other alloying elements. It is usually processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then processed by cold bending, sawing, drilling, assembling, and coloring. The main metal element is aluminum, adding some alloy elements can greatly improve the performance of aluminum profiles. [0003] With the continuous development of the aluminum product processing industry, the application of aluminum profiles is becoming more and more extensive, and the performance requirements for aluminum profiles are also getting higher and higher. However, the plasticity and tensile properties of the aluminum profiles in the prior...
