High Strength 4 Meters Long Corrosion Resistance 2024 Seamless Aluminum Tubing
2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is reasonable and the overall performance is better. Many countries produce this alloy, which is used in duralumin. The characteristics of the alloy are: high strength, a certain degree of heat resistance, and can be used as working parts below 150°C. At temperatures higher than 125°C, the strength of 2024 alloy is higher than that of 7075 alloy. The forming properties in the hot state, annealing and new quenching state are better, and the heat treatment strengthening effect is significant, but the heat treatment process is strict. The corrosion resistance is poor, but it can be protected by covering it with pure aluminum; it is easy to produce cracks, but it can also be riveted by special technology. It is widely used in aircraft structures, rivets, truck wheels, propeller components and various other structural parts.
