Generally, 7075 aluminum plate needs aging treatment in production. The purpose of aging treatment is mainly to obtain better strength and hardness. Is it true that the longer the aging time, the higher the hardness?Here are 7075 aluminum plate manufacturers to introduce in detail.

In fact, it is not that the longer the aging time is, the higher the hardness is. After the aging of 7075 aluminum plate is prolonged, the hardness gradually increases. When it reaches the peak, it first decreases rapidly and then decreases slowly.At the beginning, the hardness of 7075 aluminum plate increased slowly because it was in the incubation period. During the incubation period, the structure of 7075 aluminum plate changed very little.With the extension of time, the hardness of 7075 aluminum plate gradually increases, when the hardness reaches the peak, the equilibrium phase R generated inside the 7075 aluminum plate will lead to the decline of the hardness of 7075 aluminum plate.

Therefore, it can be seen that the longer the aging of 7075 aluminum plate is, the better, and artificial aging of 22s 0C x 12 h is a more optimal choice.

The longer the aging of 7075 aluminum plate is, the higher the hardness is. If you want to consult the price of 7075 aluminum plate, you can contact us.
