Bedra Wire’s Blac layer for wire EDMs is said to provide a departure from conventional Gamma class wires. Blac Technology provides a reconstituted structure featuring a microstructured surface infused with semiconductor aggregates. This specialized composition is designed to provide uniform distribution and embedding of particles throughout the surface.

According to the company, benefits of the technology include enhanced energy transfer during each spark, resulting in increased material removal rates. Moreover, the consistent particle distribution within the coating promotes stability and allows for a higher percentage of cutting pulses, leading to a faster cutting rate.

Blac Technology wire comes in two versions: Blacspark H, engineered for high tensile strength and recommended for up to four cuts, will be available initially in diameters of 0.20, 0.25 and 0.30 mm; and Blacspark S, a softer version tailored for taper cutting, will follow in early summer. It is also recommended for four cuts and will launch in diameters of 0.25 and 0.30 mm.

Both products will be compatible with DIN160, DIN200, P5, P10 and P15 spool types. While differing in tensile strength, both Blacspark H and Blacspark S are designed to maximize energy efficiency.
