What raw materials are needed for the production of aluminum tubes?

The purpose of aluminum tubes is to make the billets evenly arranged and have the greatest plastic deformation ability. For example, the final rolling temperature of aluminum alloy hot rolled slabs is 280~330 ℃. After rapid cooling at room temperature, the work hardening phenomenon cannot be completely eliminated. Especially for aluminum alloys strengthened by heat treatment, the natural aging process stops relatively slowly after rapid cooling.

The stop of the artificial aging process is relatively fast. The aging process after quenching will make the alloy strengthen and soften. The characteristics of these changes can be explained by the isothermal aging curves at different temperatures. The recrystallization process can not be completed, and the supersaturated solid solution can not be completely synthesized and still preserve a local work hardening and quenching effect.

It is difficult to continue to stop cold rolling without annealing, so it is necessary to stop slab annealing. After annealing, the grains are randomly oriented, that is, the deformation texture of 5052 aluminum plate disappears, and the annealing texture does not occur. This situation is rare. The recovery process mainly touches on the composition and growth of sub crystals, so the recovery texture and deformation texture are the same, and the annealing recrystallization texture and deformation texture are usually different.
