CERMET

  • Super micro grain structure improves wear and fracture resistance.
  • It covers a wide application range and thus reduces the number of tools required.
 NX2525
Micro-Strunture of NX2525		 NX2525 has high hardened Ti compound particles within it's microstructure therefore the grade has both excellent wear and fracture resistance properties.
