Introduction of 7075 Aviation Aluminum Tube
7075 aviation aluminum tube is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 is one of the commercial force alloys. After heat treatment, very high strength properties can be achieved. The 7075 material is generally added with a small amount of copper, chromium and other alloys. Among the series, the 7075-T651 aluminum alloy is particularly high-quality, known as the aluminum alloy product, with high strength and far better than any mild steel. This alloy has good mechanical properties and positive reaction.
7075 aviation aluminum tube mainly contains zinc element. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, a super-hard aluminum alloy with good wear resistance. The 7075 aviation aluminum tube is stressed and will not be deformed or warped after processing. Detection can ensure no blisters and impurities. 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness is high. 7075 is an aluminum alloy with high hardness and hardness, which is often used in the manufacture of aircraft structures and futures. It requires high-strength structural parts and mold manufacturing with high strength and strong corrosion resistance.

Application of 7075 aviation aluminum tube
7075 aviation aluminum tube 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.
