The aluminum coil manufacturer introduces which aluminum sheet materials can be processed and bent.

The hardness of the aluminum alloy sheet is very important to whether the bending cracks or not. The hardness of the aluminum alloy sheet is too high and it is easy to crack. The hardness of the aluminum alloy sheet is related to the grade and state of the sheet.

Bendable aluminum sheet series: general 1 series, 3 series, 5 series and other bendable aluminum sheets.

Aluminum sheet grade series that do not need to be bent: 6 series and 7 series have high hardness. Aluminum coil manufacturers generally deliver in the state of medium-thick aluminum sheet, and do not need to be bent. If they are bent, they must be annealed to 0 degrees. Fold again.

The relationship between the shape of the aluminum plate and its bending deformation.

The hardness of pure aluminum is not too high, and the commonly used ones are 1060, 1100, 1050, etc., which can be bent;

3 series aluminum-manganese alloy sheet: 3003, 3005, 3A21, etc. can also be bent;

5 series aluminum-magnesium alloy sheet, 5052H32 is more commonly used, no cracks after being folded 90 degrees.

The relationship between the shape of the aluminum plate and its bending deformation.

Aluminum plate state is divided into full hard, semi-hard, soft (usually called O state)

Hard state: Full-hard bending is basically not very good, such as H18, H19, H38, etc. are all full-hard, 6061, 2024, 7075T6, T651 are hardened plates, and cannot be full-hard;

Semi-hard state: Semi-hard aluminum sheet can basically be bent, such as H24;

Soft state: 0 state, 5052-0 state, 5083-0 state, etc., soft bending is definitely no problem, and the bending angle is also 180 degrees. The aluminum coil manufacturer reminds everyone to use this state, which is suitable for some special Use the product. Because it is too soft and low in strength, the applicable range is relatively small-small.
