Aluminum tubing is a kind of non-ferrous metal pipe, which is made of pure aluminum or aluminum alloy and extruded into a hollow metal tube along its longitudinal length. Aluminum tube is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in annealing, quenching and hot state, and has good spot welding property. When gas welding and argon arc welding are used, aluminum tube tends to form intergranular cracks. After quenching and cold work hardening, the machinability of aluminum tube is good, but it is poor in annealed state. Because of its low corrosion resistance, anodizing and painting methods or adding aluminum coating on the surface are often used to improve the corrosion resistance. It can also be used as mold material. I will show you some basic information of the aluminum tubing in this article.
