How about the performance of forged aluminum 7075

7075 forged 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 forged 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;

Welding performance is poor; there is a tendency for stress corrosion cracking; it needs to be used with aluminum cladding or other protective treatments. 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.

Forging aluminum 7075 typical uses:

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.

Forged aluminum 7075 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.
