7075 aluminum introduced 7075, a cold finished aluminum wrought alloy, high strength, high stiffness, far better than mild steel. 7075 aluminum alloy is one of the most powerful commercial, general corrosion resistance and good mechanical properties and the anode reaction. Deep drilling, fine grain makes a better performance, tool wear, thread rolling and differentiated in density requires less time, relatively high hardness metal material of choice. 7075 About 7075 aluminum case of Al-Zn-Mg-Cu based hard aluminum alloy 7075 in the late 1940s had been used in aircraft manufacturing, it is still widely used in the aviation industry to obtain ultra high strength wrought aluminum alloy. The feature is good plasticity after solution treatment, heat strengthened particularly effective at below 150 ℃ high strength, and has particularly good low temperature strength; welding performance is poor; there is a tendency to stress corrosion cracking; subject clad aluminum or other protection process to use. Two-stage aging can improve the ability of the alloy resistance to stress corrosion cracking. Plastic in the annealed and quenched just slightly lower than the same state of 2A12. Slightly better than the 7A04, static fatigue plate. Notch sensitivity, stress corrosion better than 7A04, which the 7075-T651 state especially the top grade, known as aluminum Alloy best products, high strength, far better than mild steel. This alloy has good mechanical properties and the anode reaction is typical of aerospace aluminum alloy. 7075-T651 aluminum mechanical properties of tensile yield strength Mpa Mpa Elongation% volume expansion coefficient m3 (.m3.k) ˉ1 20 ℃ volume resistivity conductivity IACS 20 ℃ NΩ.M elastic modulus E / Gpa Hardness HB density kg.mˉ1 525 503 11 68 * 10ˉ6 33 52.2 71 150 2820 7075 7075 Typical uses state: O, T6, T73, T76 plate. 7075 Status: O, T651, T7351, T7651 thick material 7075 state: O, T6, T173 drawing tube 7075 state: O, T6, T6510, T6511, T73, T73510, T73511, T76, T76510, T76511 extruded tube, type , rods, wire 7075 Status: O, H13, T6, T651, T73, T7351 rolled or cold bar 7075 state: O, H13, T6, T73 cold wire 7075 state: T6, T73 rivets, wire 7075 Status:?

Good plasticity after solution treatment, heat strengthened particularly effective at below 150 ℃ high strength, and has particularly good low temperature strength, poor welding performance, there is a tendency to stress corrosion cracking, two-stage aging can increase the resistance to SCC.

Features 7075 zinc as major alloying elements aluminum, but sometimes have to add a small amount of magnesium and copper. Which is super-hard alloy containing zinc, lead, magnesium and copper alloys, close to the hardness of steel, can be heat strengthened, a high-strength, heat treatable alloy, corrosion resistance of ordinary, good mechanical properties. 7075, a cold finished aluminum wrought alloy, high strength, far better than mild steel. 7075 aluminum alloy is one of the most powerful commercial.
