Density: 2.78 g/cm³ (0.100 lb/in³) Melting Range: 475°C-635°C (887°F-1175°F) |
| Welding: |
| 7075 is considered difficult to weld due to its high susceptibility to cracking, particularly in the heat-affected zone. Welding should be approached with care, and specialized techniques may be required. |
| Corrosion Resistance: |
| 7075 has good corrosion resistance, but it is not as corrosion-resistant as some other aluminum alloys. Its corrosion resistance can be further improved with protective coatings. |
| Considerations |
| 7075 is known for its high strength, excellent fatigue resistance, and good machinability. The alloy is heat-treatable, allowing for enhanced mechanical properties through post-fabrication heat treatment processes. |
