Overview of 7075 aluminum plate
The main auxiliary alloying element of 7075 aluminum plate is zinc, which has the characteristics of high strength and high hardness, which is far better than mild steel.
Huawei 7075 aluminum plate, in the production process and pays attention to product quality, can be produced in O state, T6, T651 and other states, and the produced products meet the requirements of high strength and corrosion resistance.
Typical Applications
7075 is mainly used in the manufacture of aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower wing panels, stringers, etc. After solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low temperature strength, poor welding performance, and tendency to stress corrosion cracking.
It is also widely used in mold processing, mechanical equipment, fixtures, aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf ball head, shoe mold, paper mold, foam molding mold, dewaxing mold, machinery Equipment, used to make high-end aluminum alloy bicycle frames.

7075 grade aluminum sheet performance advantages
1. The trace element Zr is added to improve the penetration, weldability, fracture toughness and corrosion resistance of the 7075 aluminum plate.
2. The high thermal conductivity of 7075 aluminum plate can shorten the forming time and improve the work efficiency.
3. Since the heat-affected part of the welding is solid-solubilized during heating, the strength can be recovered when natural aging is performed later, thereby improving the strength of the welded seam.
