7075 is an ultra-high-strength aluminum alloy belonging to the Al-Zn-Mg-Cu series, offering near-steel strength with lighter weight. It is widely used in aerospace, military, and high-end mechanical applications.
| Element | Content (%) |
|---|---|
| Aluminum (Al) | 87.1 – 91.4 |
| Zinc (Zn) | 5.1 – 6.1 |
| Magnesium (Mg) | 2.1 – 2.9 |
| Copper (Cu) | 1.2 – 2.0 |
| Chromium (Cr) | 0.18 – 0.28 |
| Others | ≤ 0.15 |
Key Features:
Ultra-high strength (T6 temper tensile strength: 500-570 MPa)
Good fatigue resistance
Heat-treatable (T6 tempers)
Poor weldability (requires special processes)
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| O (Annealed) | 230-260 | 105-140 | 12-16 | 60-75 |
| T4 | 330-400 | 230-280 | 10-15 | 90-110 |
| T6 | 500-570 | 430-480 | 5-10 | 150-160 |
Notes:
T6 temper: Highest strength but lower toughness
✅ Ultra-high strength: ~2x stronger than 6061
✅ Excellent machinability
✅ Outstanding strength-to-weight ratio
❌ Moderate corrosion resistance (requires surface treatment)
❌ Poor weldability (recommend mechanical fastening)
Aerospace: Aircraft structural components, landing gear
Military: Firearm parts, armored vehicles
Sports Equipment: High-end bicycle frames, climbing gear,
Mold Manufacturing: High-load injection molds
Heat Treatment: T6 treatment maximizes strength
Machining: Carbide tools recommended
Surface Treatment: Anodizing or coating advised for corrosion protection
Joining Methods: Prefer mechanical fastening over welding
| Alloy | Advantages | Disadvantages |
|---|---|---|
| 7075 | Ultra-high strength | Poor corrosion resistance, higher cost |
| 6061 | Balanced properties | Lower strength |
| 2024 | Excellent fatigue resistance | Poor corrosion resistance |
7075 aluminum tubes are ideal for extreme strength applications, particularly where weight reduction and high load-bearing capacity are critical. For corrosion resistance, consider surface treatments or other 7xxx series alloys.
