Can the aluminum plate be bent 5mm? Many alloy aluminum plates can be bent because the bending process has little to do with the quality of the plate.
Theoretically, aluminum plates of any thickness can be bent, and 5mm aluminum plates are thick plates. Of course, the bending effect is related to the state of the plate. The states are divided into full hard state, semi-hard state, and soft state (usually the soft state is called O state). The hard bending effect is basically not good (the aluminum plate status is H18, H19, H38, etc., which are all hard). Aluminum plates in a semi-hard state can basically be bent (H24 is semi-hard). Bending in the O-state is definitely no problem, but because it is too soft, it is basically rare for aluminum plates in this state to bend.
The bending effect of the aluminum plate is also closely related to the alloy series of the plate. The hardness of pure aluminum (1100, 1050, 1060, etc.) is not good, the only better one is 1100 H26, used for bending. Aluminum alloy has good hardness and can be used in semi-hard states such as 3003, 3005, and 5052.
It is recommended to confirm the specific situation with samples. If the hardness is too high, especially in the T6 state, bending should be performed. Mold aluminum plates are usually in T6 condition. Unless heated and folded, the difference between aluminum plates and inferior aluminum plates lies in their oxidation properties. There are differences in tolerances, surface effects, crystal precision and uniformity stability, but only the bending effects are not much different. If the aluminum surface is painted, the quality will not be good. It's also a waste of something useful. It is recommended to use 3003-H26, 3005H24 or 5052H34.
