對于鋁板狀態(tài)我們按照全硬、半硬、軟態(tài)來進行區(qū)分，通常的軟態(tài)主要是指鋁板O態(tài)，全硬的折彎效果基本不太行，在鋁板狀態(tài)里一般H18、H19、H38等都是全硬的，半硬狀態(tài)的鋁板基本上都可以折，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態(tài)的折彎一般是沒什么問題，不過由于該狀態(tài)鋁板太軟，我們一般很少用這種狀態(tài)的鋁板來進行折彎，同時我們在選擇鋁板時還要注意純鋁板和合金鋁板的區(qū)分，一般純鋁的硬度都不會太高，具體到純鋁折彎可以用1100、1050、1060等，建議用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.

合金鋁板硬度會好一點，一般可以用3003、3005、5052等半硬狀態(tài)的鋁板來折彎。如果用6061、2024、7075由于硬度太高，特別是T6狀態(tài)的更是，應該折彎不了，除非你加溫再折，好鋁板與差鋁板的區(qū)別是氧化性能、公差、表面效果、晶精度及均勻穩(wěn)定性等有區(qū)別的，單單折彎效果區(qū)別不大， 如果鋁板表面做烤漆的話質量不建議用太好的，可以考慮用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.
