Hybrid Cermet Three attributes of the Hybrid Technology contributes to superior surface finish and machining stability General use TN620 / PV720 High speed / Continuous TN610 / PV710 Special Surface-Hardened “Hybrid Structure” Excellent fracture resistance with the surface-hardened layer using the gradient composition technology. Good balance of stable wear resistance and fracture resistance by continuously-varied hardness. TN620's inner structure has high toughness and chipping resistance as well as thermal shock resistance. And surface area has higher hardness and wear resistance compared to the conventional super micro-grain cermet A.
