1, 7075 aluminum alloy is a cold-treated forging alloy, high strength, far better than soft steel. 7075 is one of the most powerful alloys for commercial use. Subject to heat treatment, very high strength properties can be achieved. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075-T651 aluminum alloy is especially top grade, which is known as the best product in aluminum alloy.

Among them, 7075-T651 aluminum alloy is especially top grade. It is known as the best product in aluminum alloy, with high strength and far better than any mild steel. This alloy has good mechanical and anodic reaction.
2, 7075 mainly contains zinc. Also belonging to the aviation series, it is aluminum-magnesium-zinc-copper alloy, which is a heat-treatable alloy. It belongs to super-hard aluminum alloy and has good wear resistance. The 7075 aluminum plate is stress-relieved and will not be deformed or warped after processing. All super-super The thick 7075 aluminum plate is ultrasonically detected to ensure no blisters and impurities. The 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness of 7075 is a high hardness, high strength aluminum alloy, commonly used in the manufacture of aircraft structures and futures. It requires high-strength structural parts and molds with high strength and corrosion resistance.
7075 is mainly used in the manufacture of aircraft structures and other high-stress structural parts requiring high strength and corrosion resistance, such as aircraft, lower wing panels, purlins, etc. Good solution after solution treatment, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low temperature strength, poor welding performance, stress corrosion cracking tendency. Also widely used in mold processing, mechanical equipment, fixtures, aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, shoe mold, paper mold, foam molding, dewaxing mold, machinery Equipment, used to make high-end aluminum alloy bicycle frame. In 2014, it will be used for the first time as the body material of the smartphone OPPO N3.
