  • NX2525 for high speed milling.
  • NX4545 for general milling.

Micro-Strunture of NX2525 Micro-Strunture of NX4545
  • NX2525 has high hardened Ti compound particles within it's microstructure there-fore the grade has both excellent wear and fracture resistance properties.
  • NX4545 uses a special alloy for the binder material therefore the grade has high fracture resistance properties.
