Introduction of 2024-T4 aluminum tube

2024 aluminum tube has high strength and certain heat resistance 2024 is a typical hard aluminum alloy in aluminum, copper and magnesium systems. Its composition is reasonable and its comprehensive properties are good. Many countries produce this alloy, which is used in duralumin. The alloy is characterized by high strength and certain heat resistance. It can be used as working parts below 150 °C. When the temperature is higher than 125 ° C, the strength of 2024 alloy is higher than that of 7075 alloy. The formability is better in thermal state, annealing and new quenching state, and the strengthening effect of heat treatment is remarkable, but the requirements of heat treatment process are strict. Poor corrosion resistance, but it can be protected by coating with pure aluminum; It is easy to produce cracks, but special technology can also be riveted.

Features of 2024-T4 aluminum tube

This is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity in the quenched and just quenched state, good spot welding, and the tendency to form intergranular cracks during gas welding. The machinability of the alloy is good after quenching and cold work hardening, and low machinability after annealing: low corrosion resistance, Anodizing and painting methods or aluminum coating on the surface are often used to improve its corrosion resistance.
