Brass wire OB-P wire/OB-B wire
This wire is the basic type in the series. It is available in two types,hard (P type) and soft (B type) this wire exhibits maximum EDM performance in a general-purpose, standard grade, or other wire EDM machine.
Features
- The wire diameter is controlled and manufactured to a tolerance of +/-0.001mm.
- Stable mechanical and electrical characteristics are guaranteed as a result of our unique heat treatment technology.
- Has excellent straightness to facilitate automatic threading.
- Uses high purity material containing minimal impurities.
