? 7075-T651 aluminum Dongguan Sen and Metal Materials Co., is a world-renowned brand agents aluminum, aluminum coil, aluminum rod and other professional Alcoa aluminum supply of imported brands are: Alcoa ALCOA, Alcan ALCAN, Aleris ALERIS, Sumitomo, Nippon Light Metal, Kobe Steel KOBELCO, Korea NOVELIS, Russia KUMZ etc; the supply of domestic brands are: China Aluminum Corporation (a subsidiary of Northeast Light Alloy, SWA, Northwest Aluminum), and other well-known brands. ? 7075-T651 aluminum 7075 aluminum case of Al-Zn-Mg-Cu based hard aluminum alloy 7075 in the late 1940s had been used in aircraft manufacturing industry, the aviation industry is still widely used in ultra-high-strength and deformation Aluminum. Its characteristics are 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; subject clad aluminum or other Use protective treatment. Two-stage aging can improve the ability of the alloy resistance to stress corrosion cracking. Plasticity in the annealed and quenched state just slightly lower than the same state 2A12. Slightly better than the 7A04, static fatigue plate. Notch sensitivity, stress corrosion better than 7A04, which 7075T651 especially the top grade, known as the aluminum is the most excellent products, high strength, far better than mild steel. This alloy has good mechanical properties and the anode reaction, is a typical aircraft aluminum. Zinc is the main alloying elements in series, adding a magnesium alloy containing 3% to -7.5% zinc, and can form a significant strengthening effect of MgZn2, the effect of the heat treatment of the alloy is far better than aluminum - zinc binary alloys. Increase in zinc alloy, magnesium content, the tensile strength will be further improved, but its resistance to stress corrosion and exfoliation corrosion will fall. After heat treatment, can achieve very high strength characteristics. The Department of Materials usually a small amount of copper, chromium and other alloys, which the department in 7075-T651 aluminum especially the top grade, known as the best product in aluminum alloy, high strength, far better than mild steel. This alloy and having good mechanical properties and the anode reaction. Representative uses include aerospace, tooling, machinery and equipment, fixture, especially for high-manufacture of aircraft structures and other requirements of strength, corrosion resistance and strong high-stress structure. ? 7075 -T651 chemical composition of the alloy (with the highest percentage, unless the list is a range of values) Si Si Fe Cu Fe Cu Mn Mg Mg chrome manganese zinc Zn Cr Ti titanium aluminum each other elements 1.20-2.0 Total 0.4 0.5 0.30 0.20 0.05 0.15 2.10-2.90 0.18-0.28 5.10-6.10 margin mechanical properties of aluminum 7075-T651?? tensile yield strength Mpa Mpa Elongation% volume expansion coefficient m3 (.m3.k) ˉ1 20 ℃ volume conductivity IACS 20 ℃ resistivity NΩ.M elastic modulus E / Gpa Hardness HB density kg.mˉ1 524 462 11 68 * 10ˉ6 33 52.2 71 150 2810 7075 Features an aluminum, high-strength heat treatable alloys. ? 2, good mechanical properties. ? 3, use good. ? 4, ease of processing, good wear resistance. ? 5, corrosion resistance, good oxidation resistance. ? 6, a good effect of the anodic oxidation of various well-known domestic and international distribution company specializing in mold steel, aluminum, material processing and heat treatment, such as wholesale sales, in order to meet user demand for high-quality materials, especially for the American ALCOA, Japan KOBELCO, Germany Corus, Taiwan's China Steel, SWA, jungle Nanshan quality aluminum, the main multi-grade specifications excellent prices. ?
