5005 Aluminum Coil
5005 Aluminum Alloy: The Versatile Magnesium-Enhanced Solution for Industrial Applications
Premium-Grade Alloy with Balanced Performance
5005 aluminum alloy (UNS A95005) delivers exceptional corrosion resistance and medium strength through its 0.5-1.1% magnesium content. This non-heat-treatable alloy achieves 145-160 MPa tensile strength (ASTM B209) while maintaining 11% elongation – outperforming 3003 alloy in marine environments with 0.03 mm/year corrosion rates.
Key Advantages:
- Corrosion Resistance: 3x better than 6061 in saltwater
- Formability: 15% elongation in H32 temper
- Weldability: 90% joint efficiency with 5356 filler
- Cost Efficiency: 20% lower than 5052 alloy
