075 aluminum alloy is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one of the most powerful alloys commercially available.
The 7075 aluminum alloy has a compact structure and strong corrosion resistance, which is best for aviation and marine plates. General corrosion resistance, good mechanical properties and anode reaction. The finer grains make the deep drilling performance better, and the tool wear resistance is enhanced.
Aluminum alloy 7075 zinc is the main alloying element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the alloy’s heat treatment effect far better than aluminum-zinc binary alloys. Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its resistance to stress corrosion and spalling corrosion will decrease accordingly. After heat treatment, very high strength characteristics can be achieved. The 7075 material is generally added with a small amount of copper, chromium and other alloys. Among the series, the 7075-T651 aluminum alloy is especially the top grade. It is known as the best product among the aluminum alloys. It has high strength and far better than any mild steel. This alloy also has good mechanical properties and anodic reaction. Representative applications include aerospace, mold processing, mechanical equipment, tooling and fixtures, especially for the manufacture of aircraft structures and other high-stress structures that require high strength and strong corrosion resistance.
7075 aluminum plate is a cold-treated forging alloy with high strength and hardness, far better than mild steel. 7075 aluminum plate is one of the most powerful commercial alloys, with ordinary corrosion resistance, good mechanical properties and anode reaction. The fine grains make deep drilling performance better, tool wear resistance enhanced, thread rolling more distinctive, and the first choice for metal materials with lower density requirements and higher hardness requirements.
The 7 series aluminum alloy belongs to the Al-Zn-Mg-Cu series of super-hard aluminum. This alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; need to be coated with aluminum or other Protection processing use. Two-stage aging can improve the alloy’s ability to resist stress corrosion cracking. The plasticity in the annealed and as-quenched state is slightly lower than 2A12 in the same state and slightly better than 7A04. The static fatigue and notch sensitivity of the sheet are better than 7A04. The density is 2.85g/cm3.
