bedra cobracut® 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® wire is manufactured to a tensile strength of 500 N/mm2 and comes in .008" and .010" diameter on a variety of spool sizes. It features a CuZn36 brass core with a specially treated pure zinc coating. This wire has been designed for cutting to the highest precision and surface finish. Due to its lower tensile strength and high elongation it is very well suited for taper cuts. bedra cobracut® is an excellent choice for cutting carbide and is the absolutely best choice for Vollmer EDM machines.
