What are the characteristics of 7075 aviation aluminum sheet for sale Haomei

7075 aviation aluminum sheet belongs to 7 series aluminum plate according to chemical elements. The 7075 aviation aluminum sheets are an ultra-high-strength deformed aluminum alloy of Al-Zn-Mg-Cu series super-hard aluminum, which mainly contains zinc. Alloy 7075 was used in the aircraft manufacturing industry in the late 1940s and is still widely used in the aviation industry. Some customers may ask, what are the characteristics of 7075 aviation aluminum sheets? let's introduce it together today!

Let's first take a look at the thermal characteristics of the 7075 aluminum plate. After solution treatment, the 7075 aviation aluminum sheet has good plasticity, and the heat treatment strengthening effect is particularly good. It has high strength below 150 ° C, and has particularly good low temperature strength; 7075 aviation aluminum sheet has poor welding performance; it has a tendency to stress corrosion cracking; It needs to be used with aluminum cladding or other protective treatment. Dual-stage aging increases alloy 7075's resistance to stress corrosion cracking. In the annealed and just quenched state, its plasticity is slightly lower than that of 2A12 in the same state, and slightly better than 7A04. The static fatigue of 7075 aviation aluminum sheets is sensitive to notch, and its stress corrosion performance is better than 7A04. Among them, 7075-T651 is the best grade. This is because its high strength is far superior to mild steel, so 7075-T651 is known as the best product in aluminum alloys. In addition, 7075 aluminum plate has high thermal conductivity, which can shorten the molding time and improve work efficiency.

In addition, as an aluminum-magnesium-zinc-copper alloy, it is a heat-treatable alloy, and the 7075 aviation aluminum sheets belong to a super-hard aluminum alloy plate, so we can also know that its main feature is its high hardness. Such a high hardness gives the 7075 aluminum plate good wear resistance. The 7075 aluminum plate is stress relieved and will not deform or warp after processing. Therefore, the high hardness and high strength of 7075 make it very suitable for manufacturing aircraft structures and other high-stress structural parts and molds that require high strength and corrosion resistance. In a word, 7075 aviation aluminum sheet has good mechanical properties and anodic reaction, and is a very suitable metal material for aviation. All super-large and super-thick 7075 aluminum plates produced by Haomei for sale have been ultrasonically detected, which can ensure no blisters and impurities.
