2024 drawn aluminum tubing is a typical hard aluminum alloy in the aluminum-copper-magnesium system, which has reasonable composition and good comprehensive performance. This alloy is produced in many countries and is the largest used in hard aluminum. The alloy is characterized by high strength and a certain heat resistance, and can be used as a working part below 150 °C. The temperature is higher than 125 ° C, and the strength of the 2024 alloy is higher than that of the 7075 alloy. The forming properties are better in the hot state, annealing and new quenching conditions, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. Corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; it is easy to crack when welding, but it can be welded or riveted by special process.
2024 seamless aluminum tube tubing has low density, but high strength, close to or exceed high-quality steel, good plasticity, can be processed into various profiles, have excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry The amount used is second only to steel. Products are mainly used in motorcycles, textile machinery parts, medical, electrical, automotive bicycle accessories, aviation containers and other industrial sectors and military enterprises.
