How many anti-corrosion methods are there for alumina board?

Aug 11, 2022
How many anti-corrosion methods are there for alumina board? Alumina plate and aluminum plate cannot achieve the purpose of alloy strengthening in the quenched state. The strength of the deformed aluminum alloy material that has just been quenched is only slightly higher than that in the annealed state, but the elongation is appropriately high. For finishing operations such as stretching and straightening, natural aging can start immediately after quenching, or it can start after a certain incubation period. This heat treatment process is called aging. Especially for heat-treated aluminum alloys, after rapid cooling, the recrystallization process cannot be completed, and the supersaturated solid solution cannot be completely decomposed, and part of the work hardening and quenching effects are still preserved. It is difficult to continue cold rolling without annealing. For slab annealing, regarding the selection of aluminum alloy sheet annealing process criteria, the rate of natural aging of different alloys varies greatly. Some alloys only take a few days, while some alloys take months or even years to adjust to a stable state (measured by the change in performance, the aluminum plate cannot achieve the purpose of alloy strengthening under the quenching state, and it has just been quenched. For the deformed aluminum alloy material, the natural aging process is relatively slow, and the artificial aging process is relatively active. The aging process after quenching will strengthen and soften the alloy, and its strength is only slightly higher than that of the annealed state. However, it is quite high, and under this condition, finishing operations such as stretching and straightening can be performed.
