Abstract

The invention relates to the technical field of aluminum alloy production, in particular to an aluminum alloy material and its production process; the aluminum alloy material includes components such as aluminum, nickel, chromium, manganese, magnesium, silicon, iron, copper and zinc ;The mass percent of each component is: Nickel: 0.05-0.22wt%; Chromium: 0.8-1.6wt%; Manganese: 0.024-0.032wt%; Magnesium: 0.78-1.5wt%; Copper: 3.5-5.8wt%; Zinc: 4.8-6.5wt%; The balance is aluminum and unavoidable impurities; the aluminum alloy material provided by the invention has excellent mechanical properties and mechanical properties, and can effectively Avoid scratches on the surface of the aluminum alloy profiles; in addition, the process provided by the invention 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 an 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 sashes. At present, there are more than 1,000 types of aluminum and aluminum alloy materials, and more than 440 types are routinely used, which are covered by 1XXX series to 9XXX series alloys in international conventions. Of course, many new alloy research and development congresses either do pre-research or development or application finalization according to their respective needs. With the advancement of science and technology, economic development and the improvement of people’s living standards, aluminum alloys are highly resistant to high strength, high toughness, high modulus, wear resistance, corrosion resistance, fatigue resistance, high tempe...

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 an aluminum alloy material that can meet the mechanical properties and use requirements of doors and windows.
