Copper Wire
Stellanox Steel offers high-purity, high-performance Copper Wire used across electrical, automotive, power generation, telecommunications, electronics, and welding industries. Manufactured using C11000 (ETP Copper) and C10100 (Oxygen-Free Copper), our wires offer exceptional conductivity, flexibility, and durability, and are available in bare, tinned, stranded, braided, and enameled formats.
With guaranteed dimensional accuracy, low resistance, and custom spool packaging, our copper wires meet global electrical and mechanical requirements.
What are Copper Wire?
Copper Wire is a slender, cylindrical form of copper used to conduct electricity and heat in almost every industrial and residential application. Known for its excellent ductility, resistance to fatigue, and thermal stability, copper wire is preferred over other metals for power transmission, grounding, coiling, winding, and signal transfer.
Copper wires come in solid or stranded types, and in soft annealed or hard-drawn tempers, depending on the application.
