High Mechanical Strength Lead Wire

WHISCUT lead wire

Straight and easy-to-use enameled wire with high strength, high conductivity, and high withstand voltage.

Suitable as wiring material for various precision equipment.
The ultra-thin diameter and high straightness improve wiring workability.
・Wiring for moving parts that requires strength
・Insertion into small holes and small diameter tubes, which is difficult with ultra-thin diameter copper wire.
・Improved workability for terminal preliminary soldering
