We often need to bend when processing products. Which are the best grade of aluminum sheet for bending? In fact, there are still many grades of aluminum sheet that can be bent. If the aluminum plate is only required to be bent, the most important thing is to combine the temper of the aluminum sheet.
For the temper of the aluminum sheet, we distinguish it according to the full hard, semi-hard, and soft state. The usual soft temper mainly refers to the O temper of the aluminum sheet. It is completely hard, and the aluminum sheet in the semi-hard temper can basically be folded, and the H24 is also semi-hard.
O temper aluminum sheet for bending is generally no problem, but because the aluminum sheet in this temper is too soft, we generally seldom use aluminum sheet in this temper for bending. At the same time, we should also pay attention to the distinction between pure aluminum sheet and alloy aluminum sheet when choosing aluminum sheet. Generally, the hardness of pure aluminum is not too high. Specifically, 1100, 1050, 1060, etc. can be used for pure aluminum sheet for bending, it is recommended to use 1100H26.
The hardness of the alloy aluminum sheet will be better. Generally, 3003, 3005, 5052 and other semi-hard aluminum sheet can be used for bending. If you use 6061, 2024, 7075, because the hardness is too high, especially the T6 temper, it should not be bent, unless you heat it up and then fold it. The difference between a good aluminum sheet and a poor aluminum sheet is oxidation performance, tolerance, surface effect and crystal precision. There is a difference in the uniformity and stability of the aluminum sheet, and the bending effect alone is not big. If the surface of the aluminum sheet is painted, the quality is not recommended to be too good. You can consider using 3003-H26, 3005H24 or 5052H34.
The above selections of best grade of aluminum sheet for bending are based on common situations. In actual use, it is recommended that you conduct a test before making a decision.
