对于铝板状态我们按照全硬、半硬、软态来进行区分，通常的软态主要是指铝板O态，全硬的折弯效果基本不太行，在铝板状态里一般H18、H19、H38等都是全硬的，半硬状态的铝板基本上都可以折，H24的也就是半硬的。
For the state of aluminum plate, we distinguish it according to the full hard state, semi hard state and soft state. Generally, the soft state mainly refers to the o state of aluminum plate. The bending effect of full hard state is not very good. In the state of aluminum plate, h18, H19 and h38 are generally full hard. The aluminum plate in the semi hard state can be folded basically, and H24 is also half hard.
O态的折弯一般是没什么问题，不过由于该状态铝板太软，我们一般很少用这种状态的铝板来进行折弯，同时我们在选择铝板时还要注意纯铝板和合金铝板的区分，一般纯铝的硬度都不会太高，具体到纯铝折弯可以用1100、1050、1060等，建议用1100H26的。
Generally, there is no problem with o-state bending. However, because the aluminum plate in this state is too soft, we seldom use this state of aluminum plate for bending. At the same time, we should pay attention to the distinction between pure aluminum plate and alloy aluminum plate when selecting aluminum plate. Generally, the hardness of pure aluminum will not be too high. For pure aluminum bending, 1100, 1050, 1060 and so on can be used, and 1100h26 is recommended.

合金铝板硬度会好一点，一般可以用3003、3005、5052等半硬状态的铝板来折弯。如果用6061、2024、7075由于硬度太高，特别是T6状态的更是，应该折弯不了，除非你加温再折，好铝板与差铝板的区别是氧化性能、公差、表面效果、晶精度及均匀稳定性等有区别的，单单折弯效果区别不大， 如果铝板表面做烤漆的话质量不建议用太好的，可以考虑用3003-H26、3005H24或5052H34的。
Alloy aluminum plate hardness will be better, generally can use 3003, 3005, 5052 semi hard state of aluminum plate to bend. If 6061, 2024 and 7075 are used, they should not be bent because of their high hardness, especially in T6 state. Unless you heat them up and fold them again, the difference between good aluminum plate and poor aluminum plate is oxidation performance, tolerance, surface effect, crystal precision and uniform stability. The bending effect alone has little difference, If the surface of aluminum plate is used for baking paint, it is not recommended to use too good one. 3003-h26, 3005h24 or 5052h34 can be considered.
