The curtain wall aluminum plate is mainly recognized according to the requirements of the pressure processing technology and the requirements of the material application department for the product performance. The annealing standards often used for aluminum alloy materials in industrial production include billet annealing, center annealing and product annealing, which are recrystallized textures. , The most common case of secondary recrystallization texture, natural aging can start immediately after quenching, or it can start after a certain incubation period. The speed of natural aging of different alloys is very different, and the phenomenon of work hardening cannot be completely eliminated.
Corrugated aluminum plate
The natural aging speed of different alloys is very different. Some alloys only need a few days, while some alloys need several months or even years to approach a stable state. The crystallization process cannot be completed, the supersaturated solid solution cannot be completely synthesized, and some work hardening and quenching effects are still preserved. It is difficult to continue cold rolling without annealing, so it is necessary to stop slab annealing.
It can also start after a certain incubation period. The natural aging speed of different alloys is very different. Some alloys only need a few days, while some alloys require several months to approach a stable state (functional performance). The change and balance of the change, the aluminum plate cannot achieve the purpose of alloy strengthening under the condition of quenching. For the deformed aluminum alloy material that has just been quenched, the suspension of the natural aging process is relatively slow, and the suspension of the artificial aging process is relatively sensitive. The aging process after quenching will make the alloy Strengthening and softening are produced, and the strength is only slightly higher than that in the annealed state, while the elongation is appropriately high, in which case finishing operations such as stretching and straightening can be suspended.
