KEY BENEFITS
Discover why Aluminum 7075 is the superior choice for high-stress applications.
| Benefit | Description |
|---|---|
| Exceptional Strength | Offers the highest strength of all commercial aluminum alloys, with a tensile strength comparable to steel. |
| High Strength-to-Weight Ratio | Provides maximum strength without the penalty of heavy weight, crucial for aerospace and mobility applications. |
| Excellent Fatigue Resistance | Withstands repeated loading and stress cycles, making it ideal for dynamic and structural components. |
| Good Machinability | Despite its high strength, it machines well, allowing for the production of complex and precise parts with a superior surface finish. |
| Stress-Corrosion Cracking Resistance | When properly heat-treated (e.g., T6 temper), it exhibits improved resistance to stress-corrosion cracking. |
