7075 aluminum plate is a cold-treated forged alloy with high strength and hardness, far superior to mild steel. 7075 aluminum plate is one of the strongest commercial alloys, with ordinary corrosion resistance, good mechanical properties and anodic reaction. The fine grain makes the deep drilling performance better, the tool wear resistance is enhanced, the thread rolling is more distinctive, and the metal material of choice for higher hardness requirements when the density requirements are small.

7075 aluminum plate belongs to Al-Zn-Mg-Cu series super-hard aluminum. 7075 alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft manufacturing 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 ° C, and particularly good low temperature strength; poor welding performance; Protected handling use. Dual-stage aging can improve the alloy's resistance to stress corrosion cracking. The plasticity in the annealed and just quenched state is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04. The static fatigue and notch sensitivity of the sheet is better than that of 7A04. Among them, the 7075-T651 state is particularly high-quality and is known as aluminum. The best of the alloys, with high strength, far superior to mild steel. This alloy has good mechanical properties and anode reaction, and is a typical aluminum alloy material for aerospace and military industries.

7075 Typical Use
It is used to manufacture aircraft structures and other high-stress structural parts that require high strength and strong corrosion resistance, such as aircraft upper and lower wing panels, stringers, bulkheads, etc. After solution treatment, the plasticity is good, and the heat treatment strengthening effect is particularly good. It has high strength below 150 ℃, and has particularly good low temperature strength, poor welding performance, and tendency to stress corrosion cracking. Double-stage aging can improve SCC resistance. Provided by Wuxi Hanshin Metallurgy.

Features
7075 is an aluminum alloy with zinc as the main alloying element, but sometimes a small amount of magnesium and copper are added. Among them, superhard aluminum alloys contain zinc, lead, magnesium and copper alloys, which are close to the hardness of steel, and can be strengthened by heat treatment. They are high-strength, heat-treatable alloys with ordinary corrosion resistance and good mechanical properties. Aluminum 7075 is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 aluminum alloy is one of the strongest alloys commercially available. Normal corrosion resistance, good mechanical properties and anodic reaction. The fine grains result in better deep drilling performance, enhanced tool wear resistance, and thread rolling more differentiated.
Sample size: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤ 25
Zinc is the main alloying element in 7075. Adding magnesium to the alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, so that the heat treatment effect of the alloy is far better than that of the aluminum-zinc binary alloy.
Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its resistance to stress corrosion and exfoliation corrosion will decrease accordingly.
After heat treatment, very high strength properties can be achieved. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, the 7075T651 aluminum alloy is particularly high-quality, known as the best product in aluminum alloys, with high strength and far better than any mild steel.
