  • Superior automatic threading capabilities due to its excellent straightness
  • Suitable for any automatic wire threading function of any wire EDM machine manufacturer
  • Offered in .004” - .012” diameter
  • High tensile strength of 980 N/mm2 for 0.004” - .008” diameter wires
  • High tensile strength of 932 N/mm2 for .010” and .012” diameter wires
  • Wire diameter tolerance +/- .00004”
  • Minimal elongation of 0.4%

Characteristics of Hitachi Soft brass wire:

  • Significantly reduced amount of brass powder/shavings makes this EDM wire suitable for automatic threading on most machines despite its lower tensile strength
  • Offered in .008” - .012” Diameter
  • Tensile strength of approx. 441 N/mm2 to accommodate taper cutting
