Single Source Technologies offers Hitachi’s standard hard brass, soft, and super soft brass EDM wires. All three of these offer a level of consistency and quality unequaled by other brands in the industry.
Characteristics of Hitachi Hard brass EDM wire:
- High cutting speed due to its zinc-rich constitution (60/40 brass)
- 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
- Wire diameter tolerance of +/- .00004”
- Elongation of >= 15%
Characteristics of Hitachi Super Soft brass wire:
- Suitable for wide angle (20° - 45°) taper cutting
- Tensile strength of approx. 441 N/mm2
- Elongation of > 25%
