It is mainly used as the material of choice for aerospace equipment, and it is also widely used in various processing and manufacturing fields such as machinery and molds.

Features of 7 Series Aluminum Sheet

7075 refers to a commonly used alloy in the 7 series aluminum alloy. The most common aluminum alloy is the 7075 alloy. It is widely used in CNC cutting and manufacturing parts, and is suitable for aircraft frames and high-strength accessories. The 7-series aluminum alloy contains zinc and magnesium elements. Zinc is the main alloying element in this series, so the corrosion resistance is quite good, and the addition of a little magnesium alloy allows the material to achieve very high strength after heat treatment.

The 7 series aluminum alloy belongs to the Al-Zn-Mg-Cu series super-hard aluminum, which 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 of the plate is sensitive to notch, and the stress corrosion performance is better than that of 7A04. The density is 2.85g/cm3.

7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, A7075-aluminum alloy is the best grade, known as the best product in aluminum alloys, with high strength and far better than any mild steel. This alloy also has good mechanical properties and anodic reaction.

1. High strength heat treatable alloy.

2. Good mechanical properties.

3. Good usability.

4. Easy to process and good wear resistance.

5. T651 state enhances corrosion cracking resistance.

6. High-strength materials for high-pressure structural parts.
