7 Series aluminum alloys overview
7 series aluminum alloys are aluminum-magnesium-zinc-copper alloys, mainly zinc, but sometimes magnesium and copper are also added in small amounts. Among them, super hard aluminum alloy is the alloy containing zinc, lead, magnesium and copper, which is close to the hardness of steel.
7xxx series aluminum alloys are heat treatable alloys, which are super hard aluminum alloys with good wear resistance, slower extrusion speed than 6 series alloys, and good welding performance.
7000 series aluminum alloys also belong to aviation series, application scope: aviation (aircraft load-bearing components, landing gear), rocket, propeller, airship.
Hot selling 7 series aluminum plate -7075
The representative of 7 series aluminum plate 7075 , mainly contains zinc elements.
7075 aluminum plate is stress relieved, will not be deformed and warped after processing. 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency.
7075 is mainly characterized by high hardness, is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures and other high stress structural parts requiring high strength, corrosion resistance, mold manufacturing.

7050 aluminum sheet plate
Zn is the mainly alloy elements of 7050 aluminum sheet. Adding magnesium into the 7050 alloy which contains 3% -75% of Zn forms a significant strengthening effect of MgZn2 and makes the effect of heat treatment far better than Al-Zn binary alloy. 7050 aluminum sheet is mainly used in aerospace， mold processing， machinery and equipment， fixture， particularly high aircraft structures and other requirements of strength， corrosion resistance and strong high-stress structure.

Aluminum sheet plate standard export packing
- The aluminum plate is paperclip or laminated to ensure that the surface of the aluminum plate is intact and free of scratches;
- Plastic film ( HDPE, PVC, PE or PET etc ) protection or hard kraft paper wrapping is used to prevent moisture and rain to ensure that the aluminum plate is clean and free of dirt during transportation (each package has a moisture-proof desiccant to ensure the quality of our products in East China and South China, where there is more rain);
- Installed with wooden brackets and reinforced with steel straps to avoid collision during transportation and to ensure the geometry of the aluminum plate remains unchanged;
- For export products, we use wooden boxes and pallets with fumigation mark for packaging;
- We can also pack according to other packaging requirements of customers;
