Mingtai 7075 Aluminum Roll

Date: 2019-05-21 13:40
Introduction to 7075 Aluminum Roll 1 7075 Aluminum Roll is a cold-treated forging alloy with high strength and far better than mild steel. The 7075 aluminum coil is one of the most powerful alloys available. Common corrosion resistance, good mechanical properties and anode reaction. The fine grain size makes the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more different from the weight. 2 is Al-Zn-Mg-Cu super-hard aluminum. This alloy is an ultra-high-strength deformed aluminum alloy that has been widely used in the aircraft industry since the late 1940s.
7075 aluminum coil chemical composition: Zinc is the main alloying element in 7075. Adding magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy far better than aluminum-zinc. Element alloy. Increasing the zinc and magnesium content in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and flaking corrosion will decrease. Subject to heat treatment, very high strength properties can be achieved.
Physical properties and mechanical properties of 7075 aluminum coil: tensile strength 524Mpa, 0.2% yield strength 455Mpa: elongation 11%, elastic modulus E/Gpa: 71, hardness 150HB, density: 2810. Main uses of 7075 aluminum coil: aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, high child ball head, shoe mold, paper mold, foam molding mold, dewaxing mold, template, fixture, machinery Equipment, mold processing. 7075 aluminum roll features: 1. High strength heat treatable alloy. 2. Good mechanical properties. 3. Good usability. 4. Easy to process and good wear resistance. 5. Good corrosion resistance and oxidation resistance.
7075 aluminum coil is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 °C, and 7075 aluminum coil has particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; Used in aluminum or other protective treatments. The two-stage aging 7075 aluminum coil improves the resistance of the alloy to stress corrosion cracking.
In short, the 7075 aluminum coil is the top grade, and is known as the best product in aluminum alloy. It has high strength and is far better than any mild steel.
