Pure Copper Wire
Purity level exceeding 99.9999%
Copper Conductor
The pure copper wires we offer have a copper content of over 99.95%, and are designed to meet diverse industrial needs. Our pure copper wires are available in various configurations, including single wire, stranded wire, multi-strand wire rope, and parallel multi-wire, with diameters ranging from 0.02mm to 8.0mm. The manufacturing process to obtain quality pure copper wires includes drawing, annealing, stranding, electroplating, and insulation, ensuring consistent quality and adaptability for different applications.

Pure copper wire is widely used in sectors such as:
- Power transmission and low/medium voltage cables
- Communication and data wiring
- Automotive wiring systems
- Windings for motors and transformers
- Aerospace and railway applications
- Renewable energy systems
- Electronics and household wiring
- Low resistivity supports efficient energy transfer, ensuring suitability for power lines, telecommunications, and intricate circuit systems.
- Excellent thermal conductivity enables its use in heat dissipation applications, such as connections in electronics or heat sink components.
- High ductility allows it to be formed into fine strands or robust configurations, which makes it suitable for various uses, from micro wiring harnesses to heavy-duty cables.
- Ultra-fine diameters, starting at 0.02mm, combined with multi-strand designs, provide flexibility and resistance to bending for advanced applications.
- We provide wire spools in three different types: plastic, wood, and metal. Each option is designed to cater to specific customer preferences and ensure efficient handling and storage.
- Standard packaging options include cardboard boxes, foam boxes, wooden crates, and wooden pallets, ensuring safe transport and handling.
- Wooden packaging such as crates and pallets are made from fumigated solid wood or non-fumigated plywood. Custom packaging solutions are available based on customer requirements.
