Dongguan OUYAO 7075 aluminum alloy Co. genus Al-Zn-Mg-Cu based hard aluminum alloy 7075 in the late 1940s had been used in aircraft manufacturing, is still widely used in the aviation industry over high-strength aluminum alloy which is characterized by deformation after solution treatment plastic, 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 to the use of CCA or other protective treatment. Two-stage aging can improve the ability of the alloy resistance to stress corrosion cracking. ductility 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 the 7075-T651 especially the top grade, known as the best product in aluminum alloy, high strength, far better than mild steel. This alloy has good mechanical properties and the anode reaction is A typical aircraft aluminum 7075 chemical composition: titanium (Ti): 0.2 Silicon (Si): 0.4 Manganese (Mn): 0.3 magnesium (Mg): 2.1-2.9 iron (Fe): 0.5 Chromium (Cr): 0.18-0.28 Zinc (Zn): 5.1-6.1 Copper (Cu): 1.2-20 aluminum (minimum) (Al): Other (per) Balance: 0.05 Others (Total): 0.15 7075 Mechanical properties: coefficient of thermal expansion (20-100 ℃ ) um / mk: 23.6, melting range (℃): 475-635, conductivity 20 ℃ (68 ° F) (% ACS): 33, the resistivity of 20 ℃ (68 ° F) m㎡ / m: 0.0515 Usage : 7075 Typical uses aerospace industry, blow molding (bottles) mode, ultrasonic plastic welding mold, high child golf head, shoe, paper and plastic molding, foam molding, lost wax mold, templates, fixtures, machinery and equipment, molds high stress structure processing and other erosion resistance.
