Optimal Aluminum Alloys for Container Manufacturing
1. 5083/5086 Marine-Grade Aluminum
- Superior saltwater corrosion resistance (critical for oceanic shipping)
- Excellent weldability for container frame construction
2. 6061-T6 Structural Alloy
- High yield strength (≥240 MPa) for load-bearing components
- Ideal for corner posts and roof supports
3. 3105/3003 Alloy for Panels
- Formability for curved surfaces and ribbed designs
- Cost-effective for sidewalls and doors
