7075 Aluminum Alloy

 

7075 aluminum is a commonly used high-strength aluminum alloy with the following detailed information:

 

1. Standard:

7075 aluminum conforms to the GB/T 3190 standard, which specifies the methods for the determination of chemical composition of aluminum and aluminum alloys.

 

2. Specific chemical composition range:

- Aluminum (Al) content: minimum 90.6%

- Zinc (Zn) content: 5.1% - 6.1%

- Magnesium (Mg) content: 2.1% - 2.9%

- Copper (Cu) content: 1.2% - 2.0%

- Manganese (Mn) content: ≤0.3%

- Chromium (Cr) content: ≤0.18%

- Titanium (Ti) content: ≤0.2%

- Iron (Fe) content: ≤0.5%

- Silicon (Si) content: ≤0.4%

- Other elements: ≤0.15%

 

3. Mechanical properties:

- Tensile strength: 572 MPa

- Yield strength: ≥503 MPa

- Elongation at break: ≥11%

- Impact strength: ≥63 J

 

4. Applications:

7075 aluminum is widely used in aerospace, defense, marine, automotive, and sports equipment industries. It is commonly used in the manufacture of aircraft fuselage and structural components, vehicles, electronic devices, and high-speed sports equipment. Its excellent strength and lightweight characteristics make it the preferred material for many high-strength, lightweight, and high-speed applications.

 

5. Different conditions:

Common conditions of 7075 aluminum include T6 and T651, among others.

 

6. Advantages:

- High strength, one of the strongest commercially available aluminum alloys

- Excellent strength-to-weight ratio, particularly suitable for lightweight and high-strength applications

- Good machinability, suitable for complex mechanical processing

- Good fatigue resistance, suitable for use under high pressure and high temperature conditions

- Good corrosion resistance

 

7. Disadvantages:

- Susceptible to stress corrosion cracking

- Higher cost compared to other aluminum alloys

 

8. Most common forms:

The most common forms of 7075 aluminum include bars, sheets, and tubes.

 

9. Comparison of different country designations:

- US designation: AA 7075

- Japanese designation: A7075

- Chinese designation: 7075 aluminum

 

Summary:

7075 aluminum is a commonly used high-strength aluminum alloy that conforms to the GB/T 3190 standard. It has high strength and excellent strength-to-weight ratio. Its chemical composition includes aluminum, zinc, magnesium, copper, manganese, chromium, titanium, iron, and other elements. Common conditions include T6 and T651. Its advantages include high strength, excellent strength-to-weight ratio, good machinability, and fatigue resistance. Its disadvantages include susceptibility to stress corrosion cracking and higher cost. The most common forms include bars, sheets, and tubes. In different countries, it is designated differently, such as AA 7075 in the US, A7075 in Japan, and 7075 aluminum in China.
