7020 Aluminium Sheet

Aluminum alloy 7020 is a high-strength, heat-treatable alloy primarily used in aerospace applications, particularly in the construction of aircraft structures. It offers a good combination of strength, toughness, and corrosion resistance. Here are some details about 7020 aluminum alloy:

---

Mechanical Properties:
Tensile Strength: 52,000 psi (360 MPa) Yield Strength: 44,000 psi (305 MPa) Elongation: 9%
Physical Properties:
Density: 2.78 g/cm³ (0.100 lb/in³) Melting Range: 655°C-695°C (1211°F-1283°F)
Welding:
7020 is generally considered weldable using standard welding methods, including gas tungsten arc welding (GTAW/TIG) and gas metal arc welding (GMAW/MIG). However, welding should be approached with care, and special precautions may be necessary to avoid heat-affected zone issues.
Corrosion Resistance:
7020 offers good corrosion resistance, especially when compared to other high-strength aluminum alloys. However, its primary use in aerospace applications often involves protective coatings for additional corrosion protection.
