Insulation aluminum coil is a type of roll material made of aluminum alloy, mainly used for thermal insulation. It forms a protective layer through external wrapping to reduce heat energy loss.
Insulation aluminum coil not only provides excellent insulation performance but also has the functions of anti-corrosion, anti-rust, high thermal conductivity, and decoration. It is widely used in construction, industrial pipelines, chemical equipment, and cold chain transportation.
Insulation aluminum coil can enhance the durability of the insulation layer, wind pressure resistance, and overall service life, while minimizing heat transfer and energy loss. Common alloys include 1060 and 3003, with kraft paper or polyurethane laminates used to prevent corrosion.
- For economical applications in general environments requiring waterproofing and rust prevention, 1060 is recommended.
- For better corrosion resistance in industrial environments or higher-demand pipeline insulation, 3003 is a mature and reliable choice.
- For high-end industries (such as nuclear power and aerospace) or applications with extreme requirements for strength and fatigue resistance, 5052 should be considered.
