7075 aluminum plate is a kind of alloy aluminum plate. The main alloying element is zinc. However, in Tianjin, 7075 aluminum plate has a situation of overcapacity. The main reason is the increase of new capacity and the new capacity under the government's strong promotion. The development cost is not low, and it is impossible for the manufacturer to close all the original production volume of the 7075 aluminum plate, but the control of the production volume is not suitable for grasping. The end result is excess production.
The 7075 aluminum plate is still widely used in the aerospace industry and has been subjected to very high strength properties after heat treatment. A small amount of an alloy such as copper or chromium is usually added to the alloy of the system. Among them, 7075-T651 is a very high quality alloy with strong hardness, good mechanical properties and anodic reaction, in addition to its use in the aerospace field, it is high in other rigid strength. Some structures that are highly resistant to corrosion also play an important role. Such as blow molding (bottle) mold, ultrasonic plastic welding mold, and mold processing for the production of high-end aluminum alloy bicycle frame. This has also led to the overall uncertainty of the 7075 aluminum plate market, so that even if the production capacity is excessive, the producers cannot break the production of the 7075 aluminum plate.
In order to solve the overcapacity problem of the 7075 aluminum plate, it is also necessary to use the assistance of the government and related industries. First, the government's investment in new capacity can be slightly reduced, and then the regional management of the 7075 aluminum plate industry can be managed with more factors. Make some manufacturers with lower capacity and are not suitable for the development of 7075 aluminum plates directly shut down, reducing overcapacity.
