Copper Coil
Stellanox Steel offers premium-grade Copper Coils manufactured for applications requiring exceptional electrical and thermal conductivity, formability, and corrosion resistance. Our copper coils are precision-wound using high-purity copper such as C11000 (ETP Copper) and C12200 (DHP Copper), making them ideal for use in HVAC, electrical systems, heat exchangers, plumbing, and industrial manufacturing.
Copper coils are available in soft annealed, half-hard, and hard tempers, and in a wide range of widths, thicknesses, and inner diameters, with customizable edge and surface finishes.
What are Copper Coils?
Copper Coils are long, continuous strips of copper rolled into coils for ease of transportation, installation, and manufacturing processes. Their flexibility, workability, and excellent conductivity make them essential in applications such as refrigeration lines, air conditioners, transformers, solar panels, and roofing systems.
Coils can be easily cut, bent, brazed, or formed without losing mechanical or electrical properties.
