BEDRA Wire Introduces Blac Technology

From BEDRA - "The blac layer is significantly different than typical Gamma class wires. The blac technology is an innovative reconstituted structure that combines a microstructured surface with tiny aggregates of semiconductor materials, which are uniformly distributed and embedded into the surface. As a result more energy is transferred into the workpiece with each spark, which of course increases the amount of material removed with each spark. However, that is only part of the benefit. The consistency of particle distribution within the coating promotes better stability and a higher percentage of cutting pulses to be applied to the workpiece. The combined result is a faster cutting rate.

blac technology wire will be launched in two different versions: blacspark H, which is a high tensile strength wire recommended for up to four cuts, will initially be offered in diameters of 0.20 / 0.25 / 0.30 mm. blacspark S is a soft version designed for taper cutting and will be available in early summer. It is also recommended for four cuts and will be initially offered in diameters of 0.25 and 0.30 mm.

Both products are available with DIN160, DIN200, P5, P10 and P15 spool types. Aside from differences in tensile strength, both blacspark H and blacspark S will support the highest possible level of energy efficiency."

As partnered retailers of BEDRA, 3D Graphite and Machining will be carrying this new line of BEDRA wire as soon as it comes available. To learn more about this wire, visit the BEDRA website, or view the various different PDF's we have available on it.
