1050 Aluminum Coil
1050 Aluminum Alloy: Premium Formability & Corrosion Resistance for Industrial Applications
1050 Aluminum Coil Product Overview
1050 aluminum alloy (UNS A91050) is a commercially pure wrought aluminum containing 99.5% aluminum with enhanced copper content. This alloy delivers exceptional formability (12% elongation), high electrical conductivity (62% IACS), and superior corrosion resistance – outperforming 3003 alloy by 18% in salt spray tests (ASTM B117).
Key Advantages:
- Formability: 25% better deep-drawing capability than 1100 alloy
- Weldability: 92% joint efficiency with GTAW/TIG welding
- Thermal Conductivity: 222 W/m·K (ideal for heat exchangers)
- Cost Efficiency: 15% lower material cost than 5052 alloy
