7075 aluminum plate is a cold-treated forging alloy with high strength and high hardness, far better than mild steel. 7075 aluminum plate is one of the most powerful alloys in the industry, with common corrosion resistance, good mechanical properties and anode reaction. Fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, the thread rolling is more different from the weight, and the preferred metal material with higher hardness requirements and higher hardness requirements.

7075 aluminum alloy features

The 7075 aluminum plate is an Al-Zn-Mg-Cu super-hard aluminum. The 7075 alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft industry since the late 1940s and is still widely used in the aviation industry. 7075 aluminum plate is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 °C, and particularly good low temperature strength; 7075 aluminum plate has poor welding performance and stress corrosion cracking tendency.

7075 aluminum plate in annealed and quenched state

The plasticity of 7075 aluminum plate in the annealed and quenched state is slightly lower than that of the 2A14 aluminum sheet in the same state. The static fatigue of the plate is not sensitive to the gap, and the stress corrosion performance is better than that of the 7050 aluminum plate. Among them, the 7075-T651 state is especially top grade, which is known as aluminum alloy. The best product in the product, high strength, far better than mild steel. This 7075 aluminum alloy plate has good mechanical properties and anode reaction and is a typical aerospace aluminum alloy material.

7075 aluminum plate used to manufacture aircraft

The 7075 aluminum plate is used to manufacture aircraft structures and other high-stress structural members that require high strength and high corrosion resistance, such as upper and lower airfoil panels, purlins, and bulkheads. After solution treatment, the plasticity is good, the heat treatment strengthening effect is particularly good, the strength is below 150 ° C, and the low temperature strength is particularly good, the welding performance is poor, the stress corrosion cracking tendency is tendency, and the double-stage aging can improve the anti-SCC performance.

7075 aluminum plate characteristics

The 7075 aluminum plate is an aluminum alloy with zinc as the main alloying element, but sometimes a small amount of magnesium or copper is added. Among them, super-hard aluminum alloy contains zinc, lead, magnesium and copper alloy, which is close to the hardness of steel. It can be heat-treated and strengthened. It is a high-strength, heat-treatable alloy with ordinary corrosion resistance and good mechanical properties.

7075 aluminum plate

7075 aluminum sheet is a cold-treated forging alloy with high strength and far better than mild steel. 7075 aluminum alloy is one of the most powerful alloys in commercial use. Common corrosion resistance, good mechanical properties and anode reaction. The fine grain size makes the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more different from the weight.
