Working Principle:
In order to solve the corrosion problem of cemented carbide, Drow experts collaborated with branded WEDM machine manufacturers to create the new corrosion resistant carbide grades –PNF series.
Corrosion resistance concept works in the beginning of grade preparation by mixing the powder with corrosion inhibitor elements. Once the PNF grade carbide contacts with dielectric substance (e.g. water, lubricant etc.), a thin layer of oxide will form on the surface of the carbide for protection. It will isolate the carbide with the outside environment and thus preventing it from further corrosion, the protection is sustainable, and continuous throughout the whole machining processing.

Product Features:
The NF series corrosion free grade has the below advantages:
1.) Able to sustain in more extreme dielectric medium condition in the WEDM process, thus help to eliminate corrosion
factor due to poor filtration and also help to cut down filtration cost.
2.) Reduce extra prevention measure to avoid carbide corrosion which may affect the quality of work pieces and therefore save cost.
3.) Maintain a good surface quality after machining, improve tool life
