7010 Aluminium Alloy Properties

7010 aluminum alloy is a high-strength, good fatigue strength, and excellent stress corrosion resistance forged aluminum alloy. Its outstanding corrosion resistance makes it particularly suitable for aerospace and other high-stress applications. However, due to its poor performance at high temperatures, it is not suitable for fields that require high-temperature tolerance.

7010 aluminum alloy belongs to the 7000 series of aluminum alloys, with zinc (Zn) as its main alloying element, typically containing small amounts of magnesium (Mg) and copper (Cu). This composition gives it exceptional strength, corrosion resistance, and good damage tolerance. 7010 aluminum alloy is widely used in aerospace and other high-demand fields, especially in environments that require high strength, fatigue resistance, and superior stress corrosion resistance.

7010 Aluminium Alloy Strength Performance

• High Strength Alloy: 7010 aluminum alloy has very high strength, especially in its forged form, where its tensile strength and yield strength surpass many other common aluminum alloys. It is suitable for applications that need to withstand significant mechanical stress.
• High Fatigue Strength: 7010 aluminum alloy has a high fatigue strength, allowing it to withstand prolonged cyclic loading without cracking, making it particularly suitable for structural components in the aerospace and transportation industries that require durability.

7010 Aluminium Alloy Corrosion Resistance

• High Corrosion Resistance: 7010 aluminum alloy has excellent corrosion resistance, especially to atmospheric and marine environments. This makes it perform well in environments with high corrosive conditions (such as aircraft external structures or offshore equipment).
• Stress Corrosion Resistance: Due to its high zinc content, 7010 aluminum alloy exhibits excellent resistance to stress corrosion. This means it can resist crack propagation caused by corrosion in high-stress environments, ensuring long-term structural stability.

7010 Aluminium Alloy Applications

• Aerospace: Due to its high strength, corrosion resistance, and high fatigue strength, 7010 aluminum alloy is widely used in the aerospace field, especially in aircraft fuselage frames, wing structures, and other high-stress components. Its high strength makes it an ideal choice for large aircraft and fighter jets.
• High-Stress Structural Components: 7010 aluminum alloy is commonly used to manufacture critical components that require high strength and high fatigue strength, such as parts for aerospace, automotive, or high-load equipment.

7010 Aluminium Alloy Not Suitable for High-Temperature Environments

Not suitable for high temperatures: Despite its excellent mechanical properties, 7010 aluminum alloy performs poorly at high temperatures, making it unsuitable for applications that operate in high-temperature environments. Its strength and corrosion resistance primarily function in the normal to moderate temperature range, and at high temperatures, the alloy's strength and hardness decrease significantly.

7010 Aluminium Alloy Processing Characteristics

• Forgability: 7010 aluminum alloy is suitable for forging processes. Since it can maintain high strength and excellent corrosion resistance in the forged state, it is often used to manufacture complex-shaped and high-precision structural components.
• Heat Treatment: The alloy can further enhance its mechanical properties and corrosion resistance through appropriate heat treatment processes (such as T6 and T73 treatments).
