Novel aluminum alloy material and production process thereof

Abstract

The invention relates to the technical field of aluminum alloy production, in particular to a novel aluminum alloy material and a production process thereof. The novel aluminum alloy material comprises, by mass percentage, 0.05-0.22 wt% of nickel, 0.8-1.6 wt% of chromium, 0.024-0.032 wt% of manganese, 0.78-1.5 wt% of magnesium, 0.66-1.65 wt% of silicon, 0.45-1.2 wt% of iron, 3.5-5.8 wt% of copper, 4.8-6.5 wt% of zinc, and the balance aluminum and other inevitable impurities. The mechanical property and mechanics property of the novel aluminum alloy material are excellent, and the surface of an aluminum alloy profile can be effectively protected against scratches; and in addition, the process is simple and reasonable, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to a novel aluminum alloy material and its production process. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows that are extruded from aluminum alloy materials into frames, stiles, and fans. At present, there are more than a thousand types of aluminum and aluminum alloy materials, and more than 440 types are routinely used, which are covered in 1XXX to 9XXX alloys in terms of international conventions. Of course, many new alloys will be researched and developed according to their own needs, either in pre-research or development or application finalization. With the advancement of science and technology, the development of the economy and the improvement of people's living standards, the aluminum alloys have high strength, high toughness, high modulus, wear resistance, corrosion resistance, fatigue resistance, high temperatu...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing aluminum alloy materials, the tensile strength is still close to the yield strength, poor toughness, low hardness, no wear resistance, no impact resistance, large thermal conductivity, large thermal deformation, poor thermal stability, and cannot be improved by heat treatment mechanical strength of the material

In addition, due to the low strength of the material, aluminum alloy doors and windows are prone to scratches, which affect the appearance and performance. Therefore, there is an urgent need for a new type of aluminum alloy material that can meet the mechanical properties and use requirements of doors and windows.
