Oxygen-free copper enamelled wire in diameters from 0.05 to 4.00 mm, available in thermal classes 155 through 220°C with Grade 1, 2, and 3 insulation builds. Manufactured to IEC 60317, NEMA, and JIS standards with full electrical and dimensional verification.
Why Universal Metals
Precision Enamelled Wire for Every Application
Oxygen-Free Copper
High-conductivity oxygen-free copper base ensures superior electrical performance. Smooth surface finish and uniform roundness from precision drawing provide consistent enamel coating thickness and reliable insulation integrity across the full wire length.
Full Thermal Range
Available from Class 155 polyurethane through Class 220 polyamideimide, with polyester and polyesterimide options in between. Each thermal class optimised for its target application, from consumer electronics to industrial traction motors.
IEC / NEMA / JIS Certified
Grade 1, 2, and 3 insulation builds manufactured to IEC 60317, NEMA MW 1000, and JIS C 3202 standards. Every production lot supplied with third-party test certificates for breakdown voltage, pinhole count, and dimensional compliance.
