Electric wires using high-strength, high-conductivity copper alloy wires provided with insulation coatings.

Ideal for use as wiring materials in various types of precision devices.

Their extremely small diameters and high straightness allow them to improve wiring workability.

  • Wiring for moving parts requiring high strength.
  • Insertion into small holes or small-diameter tubes which would be difficult with extra fine copper wires.
  • Improved workability of terminal pretinning.

Whisker is a term coined from Whisker and CUT, which evokes the image of a product that is thin and supple, like a cat's whiskers, and has sensing capabilities.
