7075 aluminum sheet (Al-Zn-Mg-Cu) belongs to super-hard aluminum. As a kind of cold finished wrought alloy, it has great strength and hardness. It’s far better than mild steel. This alloy has good mechanical properties and anode reaction. 7075 aluminum sheet as a typical kind of aerospace aluminum alloy material is usually used for high-end fields.7075 aluminum is one of the most powerful commercial alloys, the general anti-corrosion properties, good mechanical properties and anode reaction. Fine grain makes the depth of drilling better performance, tool wear resistance, thread rolling and more weight is different from the smaller density requirements, the hardness of the metal material of choice for relatively high.
7075 aluminium plate/sheet Features:
Is a zinc alloy as the main alloying elements, but sometimes a small amount of added magnesium, copper. One super-hard aluminum alloy is containing zinc, lead, magnesium and copper alloy, close to the hardness of steel, heat treatment can be strengthened, is a high-strength, heat-treatable alloy, corrosion resistance in general, good mechanical properties. Aluminum 7075 is a cold forged alloy, high strength, far better than mild steel. 7075 aluminum alloy is one of the most powerful alloys. General corrosion resistance, good mechanical properties and anode reaction. The fine grain makes the depth drilling better, the wear resistance of the tool is enhanced, and the thread rolling system is different.
It is characterized by good plasticity after solution treatment, heat treatment strengthening effect is particularly good at 150 ℃ below the high strength, and has a particularly good low temperature strength; welding performance is poor; a tendency to stress corrosion cracking; subject to aluminum or other package Protection processing. Two-stage aging can improve the ability of the alloy to resist stress corrosion cracking. In the annealed and just quenched state plasticity slightly lower than the same state of 2A12. Slightly better than 7A04, plate static fatigue. Notch sensitive, stress corrosion resistance is better than 7A04, which is particularly the state of 7075-T651 top grade, known as aluminum Alloy the best products, high strength, far better than mild steel. This alloy has good mechanical properties and anodic reaction, is a typical aerospace aluminum alloy material.
7075 aluminium alloy sheet Use:
For the manufacture of aircraft structure and other requirements of high strength, corrosion resistance of high stress structural parts, such as aircraft, the lower wing surface panels, beams, frame and so on. After solution treatment, good plasticity, heat treatment strengthening effect is particularly good, 150 ℃ below the high strength, and a particularly good low temperature strength, poor welding performance, stress corrosion cracking tendencies, two-stage aging can improve anti-SCC performance.
