7075 super-hard alloy chemical composition: Si Si: 0.40 Copper Cu: 1.2 ~ 2.0 Mg Mg: 2.1 ~ 2.9 Zinc Zn: 5.1 ~ 6.1 Mn Mn: ≤0.30 Titanium Ti: ≤0.20 Chromium Cr: 0.18 ~ 0.28 Iron Fe: 0.50 Note: Single: ≤0.05; Total: ≤0.15 aluminum Al: margin material composition and process strictly controlled to ensure the standard of each batch of material composition and mechanical properties. 7075 aluminum rods physical properties and processing characteristics and mechanical properties: Tensile strength: 524Mpa 0.2% yield strength 455Mpa Elongation: 11% elastic modulus: E / Gpa:. 71 7075 aluminum Features: 1. High-strength heat treatable alloys. 2. Good mechanical properties. 3. Use good. 4. easy processing, good wear resistance. 5. corrosion resistance, good oxidation resistance are called ultra-high strength 7075 aluminum alloy, the yield strength of the alloy close to the tensile strength, yield ratio, is also high specific strength, but the ductility and high temperature strength than the end, should do room temperature, the load-bearing structural parts used below 120 ℃, alloy ease of processing, have the same good corrosion resistance and high toughness. The alloy is widely used in aviation and aerospace, and this area has become one of the most important structural materials. 7075 Introduction: 7000 Series represents 7075 containing mainly zinc. Also belong to the aviation series, aluminum-magnesium, zinc and copper alloy is heat treatable alloys, are super-hard alloy with good abrasion resistance .7075 eliminate stress without deformation 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 7075 aluminum alloy with high hardness, high strength, used in the manufacture of aircraft structures and futures. It requires high strength, corrosion resistance and high strength stress structural parts, mold manufacturing. Now basically rely on imports, China's production process to be improved. There was a foreign-made 7075 aluminum annealing uneven and inconsistent appear aluminum surface hardness internal problem for the imagination, my company specializes in technical solutions proposed: 1. China 7075 aluminum as uneven hardness, heat treatment can be repeated themselves "7075 aluminum rod" 7075 aluminum "," Shenzhen 7075 aluminum "" 7075-T6 "" 7075 aerospace aluminum, "" 7075 aluminum "2. Recommendation of the workpiece is a high-precision parts use, according to their material requirements, choose the correct import materials can be achieved when saving time, effort, efficiency of labor. 7075 is one of the most powerful commercial alloys ordinary corrosion resistance, good mechanical properties and the anode reaction drilling depth, fine grain makes better performance, wear-resistant tools enhancements, thread rolling and differentiated.
