We all know that 7075 aluminum plate has a good development in the aviation field, mainly due to its excellent performance, the excellent performance of 7075 aluminum plate can not be separated from good processing technology, which can not be separated from the aging treatment.

In the aging process of 7075 aluminum plate, the solid solubility of Zn in aluminum is very high, up to 23.s % at 548℃, and decreases rapidly with the decrease of temperature, which can produce excellent solution strengthening and aging strengthening effect in 7075 aluminum plate.In the aging process of 7075 aluminum plate precipitated (3-A12Mg3Zn3 and 3-A12Cu phase hardness and melting point are very high, good thermal stability, can effectively improve the strength and creep resistance of 7075 aluminum plate.Mg is usually added to 7075 aluminum plate, because Mg is an effective grain refining agent, mainly distributed in the grain boundary, traction, nail grain boundary effect, block dislocation movement and grain growth, so as to improve the strength of 7075 aluminum plate.

It can be seen that the aging treatment of 7075 aluminum plate is essential. In addition, you can contact us to know the price of 7075 aluminum plate.
