1.7075 aluminum plate features
What is shown in the figure is aluminum plate. There are many kinds of aluminum plate, which can be divided into about 8 series. 7 series aluminum alloy belongs to Al-Zn-Mg-Cu series superhard aluminum alloy, which has been applied in the aircraft manufacturing industry since the late 1940s and is still widely used in the aviation industry. It is characterized by good plasticity after solution treatment, especially good heat treatment strengthening effect, high strength below 150℃, and especially good low temperature strength; Poor welding performance; Stress corrosion cracking tendency; Need to be coated with aluminum or other protective treatment. Here is one of them, 7075 aluminum alloy plate. 7075 aluminum plate belongs to Al-Zn-Mg-Cu series superhard aluminum. 7075 alloy is an ultra-high strength deformed aluminum alloy that has been applied in the aircraft manufacturing industry since the late 1940s and is still widely used in the aviation industry.

4.7075 aluminum plate uses
7075 aluminum alloy is a kind of very high-strength aerospace aluminum, which is used for gear and shaft automobile parts and aircraft structures. 7075 is widely used in the construction of aircraft structures such as wing and fuselage. Its strength and light weight are also desirable in other fields. Rock climbing equipment and bicycle parts are usually made of 7075 aluminum alloy. The bicycle industry also uses 7005 and 6061 aluminum alloys. Amateur R / C Chassis generally adopts 7075-T6 and 6061.
It can also be used for goff balls, molds, precision parts and so on.
