Description

Technical Field

[0001] This utility model relates to the field of aluminum alloys, and in particular to a high-strength anodic aluminum alloy. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with added amounts of other alloying elements, and are one type of lightweight metal material. In addition to the general properties of aluminum, aluminum alloys also possess specific alloying characteristics due to variations in the types and amounts of alloying elements added. The density of aluminum alloys ranges from 2.63 to 2.85 g / cm³. 3 It has high strength (σb is 110~650MPa), specific strength close to that of high alloy steel, specific stiffness exceeding that of steel, good casting and plastic processing properties, good electrical and thermal conductivity, good weldability, and can be used as a structural material. It has wide applications in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily necessities.

[0003] Currently, aluminum alloys are typically single-layer structures, usually manufactured using single-layer aluminum alloy sheets. While this type of aluminum alloy has a simple structure, it is also relatively simple, with low strength. During use, it is easily deformed when subjected to external forces or impacts, affecting the overall structural stability and safety. Its load-bearing capacity is low, making it prone to damage or even breakage during use, posing significant safety hazards. The resulting products are of poor quality, have short service life, and offer a poor user experience. Furthermore, aluminum alloys have poor high-temperature resistance, generally unsuitable for use in high-temperature environments, failing to meet current requirements. Therefore, it is necessary to research a new technical solution to improve current aluminum alloys. Utility Model Content

The alumina film has high mechanical strength and hardness, good thermal stability, and good corrosion resistance, wear resistance, oxidation resistance and high temperature resistance.
