High-purity electrolytic copper wire (T1/T2 red copper, ≥99.9% purity).
Precision-twisted multi-strand fine copper wires (0.05–0.3 mm), forming circular, rectangular, or custom cross-sections. Compact, flexible, and highly tensile.
Bare, tin-plated, or silver-plated for enhanced oxidation resistance, corrosion resistance, and weldability.
PVC/silicone insulation or metal shielding for insulation, EMI resistance, or high-temp performance.
Twisted structure enables tight bending and vibration resistance.
Low resistance for stable high-current/signaling.
Withstands tension, compression, and fatigue.
Reliable under repeated motion.
