OKI Brass Wire (OB-PZN)

  • Wire with no paraffin coat

The PN Type is a special electrode wire most suitable fore wire electric discharge machines, which has been developed using high-speed machining and automatic threading technologies.

It yields a fine finish in machining large or precision work materials while exhibiting superior automatic theadability. The high zinc concentration in brass has assured high-speed machining.


  • This product has been certified and recommended by FANUC LTD.
  • Zinc concentration in brass has been raised (compared to conventional types), achieving a stable high-speed machining.
  • Holds excellent straightness and tensile strength at room temperature, maintaining high automatic threadability and the fine finishes of machined surface.
  • Requires cardboard boxes only for packaging with no styrenefoam, which contributes to enviromental conservation and reduces costs for industrial waste disposal.
