7050 and 7075 are both high-strength aluminum alloys that are commonly used in aerospace, military, and other demanding applications.
Chemical Composition 7050 vs 7075 Aluminum
| Grade | Al | Zn | Mg | Cu | Si | Fe | Mn | Cr |
| 7075 | Rem | 5.1 – 6.1% | 2.1 – 2.9% | 1.2 – 2.0% | ≤ 0.4% | ≤ 0.5% | ≤ 0.3% | 0.18 – 0.28% |
| 7050 | Rem | 5.7 – 6.7% | 2.0 – 2.6% | 1.9 – 2.6% | ≤ 0.12% | ≤ 0.15% | ≤ 0.1% | 0.04 – 0.15% |
Strength and Toughness:
7050 Aluminum: 7050 is known for its combination of high strength and toughness. It has slightly better stress corrosion cracking resistance than 7075.
7075 Aluminum: 7075 is known for its exceptionally high strength-to-weight ratio and is often considered one of the strongest aluminum alloys available. It might not have the same level of toughness as 7050 but is still widely used in applications where high strength is crucial.
