1200 Aluminum Coil
Available Configurations
Properties common to all products in this list
Key Features
Al 1200 Aluminum Coil is a commercially pure 1xxx series coil with a minimum aluminum content of 99.0%, combining higher tensile strength and work-hardening capacity than 1050 with the formability, corrosion resistance, and continuous-feed geometry of the 1xxx series:
Electrical & Thermal Conductivity (~55–57% IACS, ~205 W/m·K)
Higher permitted Fe+Si content than 1050 increases solid-solution electron scattering, yielding electrical conductivity of ~55–57% IACS and thermal conductivity of ~205 W/m·K — the lowest of the four 1xxx coil grades but still well above structural alloy grades.
Higher Tensile Strength & Work-Hardening Capacity than 1050
Greater Fe+Si content gives 1200 slightly higher tensile strength and more pronounced work-hardening response than 1050 at equivalent temper — providing improved dimensional stability under mechanical load in demanding forming and lamination operations.
Continuous-Feed Reel Format
The coil format enables high-volume continuous processing without joins or batch interruptions.
Naturally Passivating Oxide Layer
The self-limiting Al₂O₃ layer provides reliable corrosion and moisture barrier performance across the full coil length.
Cost-Effective High-Volume Grade
Broad availability and cost-effectiveness make 1200 the default commercial choice for high-volume industrial coil processing where maximum conductivity is not the primary driver.
Industrial Applications
Al 1200 Aluminum Coil is used in high-volume continuous processing across HVAC, packaging, cable shielding, and heat exchanger production — where mechanical durability and barrier performance take precedence over maximum conductivity:
- ✦ HVAC Duct Facing, Insulation Jacketing & Packaging Lamination
- Mechanical durability and barrier performance make 1200 the standard grade for HVAC duct facing, insulation jacketing, and high-volume packaging lamination — where 1200's additional strength over 1050 reduces deformation in handling and installation.
- ✦ Cable Shielding Wraps
- Corrosion resistance and barrier integrity across long coil lengths are the primary requirements, where 1200's higher tensile strength reduces tearing risk in high-speed wrapping operations.
- ✦ Heat Exchanger Fin Stock
- Greater stiffness than 1050 at equivalent temper reduces fin collapse under operating pressure in heat exchanger assemblies.
- ✦ High-Volume Industrial Coil Processing
- Cost-effectiveness and broad availability make 1200 the default commercial-purity choice for industrial coil processing sectors where conductivity requirements are met by the 1xxx series baseline.
- ✦ Commercial-Purity 1xxx Processing Research
- Used as a standard reference alloy in research on thermomechanical processing, work-hardening response, and conductivity of commercial-purity 1xxx series aluminum.
