The application of aluminum alloy profiles in the aviation industry

Aviation aluminum materials are several types of aluminum materials widely used in the aviation industry at this stage. They have good structural mechanics and production and processing characteristics. Compared with general aluminum materials, their structural mechanics and production and processing characteristics are much better.

Wuxi Hengtai Aerospace Technology Co., Ltd. was established in 2001. It is an enterprise specializing in the processing and distribution of high-end aluminum alloy plates. Relying on more than ten years of industry accumulation and rigorous management system, it has won a good market reputation.

Next, the editor will show you the application of aluminum alloy profiles in the aviation industry:

Aluminum alloy profiles have long been used for aviation, du60---70s 7xxx series aluminum alloy T73 and T76 heat treatment process regulations, contemporary use 7050 aluminum alloy and high-purity aluminum alloy, 7075 aluminum alloy plate belongs to daoAl-Zn-Mg- Cu-based super-carbon tool steel, 7075 aluminum alloy is an extremely high compressive strength deformable aluminum alloy profile that has been used in airport processing and manufacturing in the late 1940s and is still widely used in the aerospace industry.

Its characteristics are that the plastic deformation is good after aging treatment, and the actual effect of heat treatment is particularly good. It has high compressive strength below 150°C, and particularly good ultra-low temperature compressive strength;

Electric welding has poor welding characteristics; there is a tendency of intergranular corrosion and cracking; it must be applied with aluminum clad or other maintenance.

The bipolar aging property can improve the working ability of aluminum alloy against intergranular corrosion and cracking. The plastic deformation under quenching and just heat treatment is slightly smaller than 2A12 in the same situation. Slightly better than 7A04, the static fatigue vacancy of the plate is more sensitive, and the intergranular corrosion characteristic is better than 7A04. Among them, 7075T651 is particularly good, which is called aluminum The high-quality products among the alloy profiles have high compressive strength, far exceeding that of mild steel. This aluminum alloy has excellent physical properties and anodic oxidation reaction, and is a typical aviation aluminum.
