In the production of 2A12 aluminum plate, there are thick plate and thin plate. Cracking and deformation may occur when the 2A12 aluminum plate is quenched. What is the reason for this?So how do you do that?Next, 2A12 aluminum plate manufacturers will introduce the reasons for quenching and cracking of 2A12 aluminum plate and correct operation.

1. First of all, it may be that the quenching temperature is greater than 502℃, resulting in the over-burning phenomenon of 2A12 aluminum plate.

2. Secondly, the quenching transfer time of 2A12 aluminum plate is too long.

3. It is also possible that the cooling rate of 2A12 aluminum plate is too fast.

4. If there is no operation error above, it may be that the alloying element of 2A12 aluminum plate exceeds the standard, and the high content of Zn may increase the crack tendency during crystallization.

The correct operation of 2A12 aluminum plate quenching is:

Quenching temperature should be: 485-498℃, overburning temperature is 502℃

Aging: natural aging at room temperature for more than 96 hours

Artificial aging at 185-195℃ for 6-12 hours

The quenching transfer time shall not exceed 30 seconds, and the quenching cooling rate shall not be less than 50℃.

The reason of 2A12 aluminum plate quenching cracking and correct operation is introduced here. If you need to know the price of 2A12 aluminum plate, you can contact us.
