1mm thin sheet aluminum is suitable for bent. Whether the aluminum sheet can be bent is related to the alloy state and bending angle of the aluminum sheet. The solution-treated aluminum plate (such as 6061-T6) and the aluminum plate with high magnesium content (5083-h112) have too high hardness, and the aluminum plate is easily broken when bent, and can only bend the r angle, not 90 degrees and the edge.

First, the state of thin sheets of aluminum is important. The bending state of the thin sheet aluminium is divided into full hard, semi-hard and soft (usually called O state).

The effect of full hard bending is basically not good (the state of the thin aluminum sheet is H18, H19, H38, etc.)

Semi-hard aluminum sheet can basically be bent (H24, that is, semi-hard aluminum sheet)

O-bending is certainly no problem, but because it is too soft, it is rarely used in this state.


Secondly, should you choose pure aluminum or alloy aluminum.

The hardness of pure aluminum is not very good, you can use 1100, 1050, 1060, etc. It is recommended to use 1100H24 for aluminum sheet bending.

The hardness of aluminum alloy is slightly better, and it can be used in semi-hard states such as 3003, 3005, and 5052. The larger the bending R angle, the higher the success rate, so try to increase the bending R angle as much as possible.

In special cases, it is recommended to re-determine the sample. If you use 6061, 2024, 7075, due to the high hardness, especially the sample in T6 state, it should not be bent unless you heat it and then bend it. As soon as you think about it, everyone understands that the thin sheet aluminum should be bent with a thinner aluminum sheet as much as possible.
