Copper Drawn Wire LiOA

LiOA Copper Drawn Wire is pure copper wire processed through a multi-die cold-drawing process from Upcast copper rod, achieving small diameters and tight tolerances.
Cu purity reaches 99.994% / 99.991% (SGS certified), with electrical conductivity ≥ 100% IACS — a key conductive material for power cables, electrical wires and electronic devices.
Diameter range Ø0.5mm – 3.2mm, available in both annealed (soft) and hard-drawn states.
Bright, non-oxidized surface, produced from LiOA Copper’s in-house Upcast copper rod.
Flexible packaging by wire size, convenient for transport and feeding into production lines.

Description

LiOA Copper Drawn Wire is produced from in-house Upcast copper rod with Cu purity of 99.994% / 99.991% (SGS certified). In-house raw material control within LiOA Copper’s closed production chain ensures quality from the source and high consistency across batches.
The multi-die cold-drawing process produces wire with diameters as small as Ø0.5mm with tight tolerances, a bright and non-oxidized surface essential for uniform, high-quality end products.
Electrical conductivity of 100% IACS or higher reduces energy loss along transmission, meeting the demanding requirements of the power cable and electronics industries.
The product is supplied in both annealed and hard-drawn states, giving customers flexibility for each purpose: soft wire is easy to strand, bend and coil, while hard wire retains high mechanical strength for demanding applications.
Purity is independently verified by SGS with transparent documentation; the process holds ISO 9001 and ISO 14001 certifications — providing quality assurance for domestic customers and export partners.
