COATED CERMET

Micro-Structure of AP25N
Micro-Structure of AP25N
Coated cermet (PVD coating) has superior wear and fracture resistance, and therefore provides a stable cutting performance.
  • Coating Layer
    Outer layer is TiN(Welding resistance)Middle layer is (Al,Ti)N Compound.(wear resistance thermal shock resistance)

  • Substrate
    Micro Grain Cermet NX2525 (wear resistance and fracture resistance)
