bedra cobracut® Type W wires are part of bedra's world-renowned EDM Wire portfolio. Well known for their high quality, all bedra EDM wires are manufactured in Germany by Berkenhoff GmbH, a global leader with over 100 years of pioneering developments in non-ferrous fine wire manufacturing. Berkenhoff started drawing EDM wires as far back as 1969 and began producing brass wires in 1976.
Berkenhoff is certified to ISO 9002 and its 400+ employees include specialists in chemistry, physics, material sciences, material testing, analysis, quality control, and factory automation. Berkenhoff is globally one of the very few fully vertically integrated wire producers where the complete EDM wire manufacturing process from casting to drawing to spooling and packaging is done under one roof, assuring total control of all critical EDM wire parameters. bedra EDM wire sets the global standard for quality and consistency which translates to precise, efficient, and uninterrupted WEDM machine operation.
bedra cobracut® Type W is a soft wire manufactured to a tensile strength of 430 N/mm2, features a high copper CuZn20 brass core with a CuZn50 brass coating. It comes in .010" and .012" diameter on a variety of spool sizes. This EDM wire has been designed specifically for high tapper cutting. Its very high elongation allows this wire to lay flat and straight even during extreme taper machining. The special coating was designed to resist high thermal loads arising from poor flushing conditions.
