Introduction of 2024 Large Diameter Thick Wall Seamless Aluminum Tube
2024 aluminum tube is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better. Many produce this alloy, which is used in duralumin. The characteristics of this alloy are: high strength, certain heat resistance, and can be used as working parts below 150°C. At temperatures above 125°C, the strength of the 2024 alloy is higher than that of the 7075 alloy. The formability is better in the hot state, annealed and newly quenched state, and the heat treatment is strengthened, but the heat treatment process is strictly required. The corrosion resistance is poor, but it can be effectively protected by cladding with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by a special process, which is more and more used by the automobile and rail transit industries.
