7075 plate is a kind of high-strength 4 x 8 aluminum sheet, which is the representative grade of 7000 series aluminum alloy plate. 7075 aluminum plate is mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower fins, stringers, etc. After solution treatment, the aluminum 7075 plate has good plasticity, and after heat treatment, the strengthening effect is good, and the strength below 150 degrees is good, especially the low temperature strength is good, the welding performance is poor, and there is a tendency of stress corrosion cracking. 7075 aluminum plate is also widely used in mold processing, mechanical equipment, tooling and fixtures, etc.
As we can see, 7000 aluminum alloy is another commonly used alloy with a wide variety and it contains zinc and magnesium. Among the more common aluminum alloys, the 7075 plate alloy has the best strength, but it cannot be welded, and the corrosion resistance is quite poor, so many CNC machining parts use 7075 alloy aluminum plate. Zinc is the main alloying element in this series, and small amounts of magnesium alloys can give the material a high strength after heat treatment. This series of materials generally add a small amount of copper, chromium and other alloys. Among them, the 7075 aluminum plate alloy is particularly good in quality and has the highest strength, which is suitable for aircraft frames and high-strength accessories.
7075 plate is the most widely used product in the 7000 series 1/8 aluminum sheet. 7075 aluminum sheet is used in aviation fixtures, trucks, tower buildings, boats, pipelines and other applications that require a strong structure. Such as: aircraft parts, gears and shafts, fuse parts, instrument shafts and gears, trip valve parts, turbines, keys, aircraft, aerospace and defense applications.
