7075-T651 aluminum plate description
7075 aluminum plate is a cold treated forging alloy with high strength and hardness, which is much better than mild steel. 7075 aluminum plate is one of the most powerful alloys in business. It has ordinary corrosion resistance, good mechanical properties and anodic reaction. Fine grains make the deep drilling performance better, the wear resistance of tools is enhanced, the thread rolling is more different, and the metal material is the first choice when the density requirement is small and the hardness requirement is relatively high.
Introduction to 7075-T651 aluminum plate
7075 aluminum plate belongs to Al an mg Cu superhard alloy. 7075 aluminum plate is a product launched by Alcoa in 1943. In the aerospace industry, 7075 aluminum plate has always been the main product of 7xxx series alloy. Adding chromium alloy to Al Zn mg Cu high-strength alloy makes it a good plate product resistant to stress corrosion cracking. Because 7075 aluminum plate is the best product in aluminum alloy products, it generally has good mechanical properties and anodic reaction. Therefore, 7075 aluminum plate is a good way to balance the performance required by aerospace applications.
7075-T651 aluminum plate Properties
The hardness of 7075 aluminum plate is mainly 150HB, the density is 2810, the tensile strength is 524mpa, and the elongation is 11%. In addition to these physical properties, 7075-T651 aluminum plate is characterized by very good plasticity after solution treatment, very good heat treatment effect, high strength at 150 ℃ and relatively good low-temperature strength, but its welding performance is particularly poor and has the tendency of stress corrosion cracking, Generally, it can only be used after aluminum or other protective treatment. The main element contained in 7075 aluminum plate is zinc, but sometimes magnesium, copper and other metal elements are added together. If the content of zinc and magnesium in aluminum alloy is increased, its tensile strength will be further improved, but its resistance to stress corrosion and spalling corrosion will decrease.
