The main alloying elements 7075 of zinc, the intensity is very strong, with good mechanical properties and the anode reaction. Mainly used in the manufacture of high strength aircraft structures and other requirements, corrosion resistance of 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, at 150 degrees below have good strength, and there is poor particularly good low temperature strength, weldability, stress corrosion cracking. Also widely used in mold processing, machinery and equipment, tooling and fixtures. 7075-T6 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 Application and properties of the material containing mainly zinc 7075. Also belong to the aviation series, aluminum-magnesium zinc copper alloy, heat treatable alloy, are super-hard alloy, has good abrasion resistance .7075 eliminate stress, it will not be 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 and increase productivity. The main feature is the hardness of 7075 aluminum alloy high hardness, high strength, used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance and strong high-stress structural parts, mold manufacturing. Now basically rely on imports, China's production process to be improved 7075 technical standard 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 - Packing, marking, transportation and storage GB T 3246.1 Wrought aluminum and aluminum alloy products microstructure test method T 3880.2 General industrial aluminum and aluminum alloy sheet, strip Part 2 / GB /: Mechanical Properties GB / T 3880.3 General industrial aluminum and aluminum alloy sheet, 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 and alloy processing products tensile test specimens GB T 17432 Wrought aluminum and aluminum alloy chemical analysis sampling methods /
