The main elements of 7075-T6 aluminum alloy 7075 for zinc, strength is very strong, with good mechanical properties and the anode reaction. About 7075-T6 aluminum is mainly used for high production of aircraft structures and other requirements of strength, corrosion resistance and high stress structural parts, such as aircraft, under the wing facing the wall panels, beams and so on. Good plasticity after solution treatment, heat treatment to strengthen good effect, less than 150 degrees with good intensity, and there are poor particularly good low temperature strength, weldability, there is a tendency to stress corrosion cracking. Also widely used in tooling, machinery and equipment, tooling and fixtures. 7075-T6 aluminum component analysis Cu1.2-2.0-, Si0.4-, Fe0.5-, Mn0.315-, Mg2.1-2.9-, Zn5.1-6.1-, Cr0.4-, Ti0.06 -, 7075 and feature 7075 application materials containing mainly zinc. Also belong to the aviation series, aluminum-magnesium, zinc and copper alloy is heat treatable alloy, are super-hard alloy, has good abrasion resistance .7075 eliminate stress, not deformed after processing, warping all super super thick 7075 aluminum ultrasonic detection, can guarantee no blisters, impurities .7075 high thermal conductivity, can shorten the molding time, improve work efficiency. The main feature is the hardness of aluminum alloy 7075 is high hardness, high strength, commonly used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance and strong high-stress structural parts, mold manufacturing. 7075 technical standards commentary GB / T 228 metal materials at room temperature tensile test method GB / T 232 metal bending test method GB / T 3190 Wrought aluminum and aluminum alloy chemical composition of GB / T 3199 aluminum and aluminum alloy products packaging, labeling, transportation , storage GB / T 3246.1 deformation microstructure of aluminum and aluminum products inspection method GB / T 3880.2 general industrial aluminum and aluminum alloy sheet, strip, Part 2: Mechanical properties of GB / T 3880.3 general industrial aluminum and aluminum alloy plate strip Part 3: size deviation GB / T 6987 (all parts), chemical analysis of aluminum and aluminum alloys GB / T 7999 aluminum and aluminum photovoltaic (photometry) emission spectrometry method GB / T 16865 Wrought aluminum, magnesium its alloy processing products tensile test specimens with GB T 17432 Wrought aluminum and aluminum alloy chemical analysis sampling methods /
