Cermet
1
Coated Cermet Cermet consists of a hard phase and a binding phase, which is the case with
“Premium
Grades Ti (C, N, O) base cemented carbides. The hard phase consists mainly of Titanium carbide TiC
-Coating”
and Titanium nitride TiN. These carbides and nitrides have superior strength
and oxidation resistance when working at high temperatures when compared
Increasing wear resistance (hardness) Increasing impact resistance (toughness) GT9530 ensures high crater resistance. Finally, Cermet grades are applicable to high
with Tungsten carbide WC.
Furthermore, there is little tendency to react with the work material and this
and low speed cutting ranges while delivering excellent surface roughness.
For Turning “Super fine Cermets” GT730, NS730 and
our NEW NS9530 and GT9530
Cermet creates a high quality surface finish due to the combination of “Fine-
grain reinforcement technology” and “Surface smoothing technology”. This
improves the impact resistance, which is generally a weak point of Cermet.
n“Fine-grain reinforcement technology”
This technology enhances the reliability and performance of the grade. It
offers improved wear and impact resistance with its high bonding strength,
heat resistant Titanium compound and fine bonding grain Titanium
compound that prevents crack propagation and improves toughness.
n“Surface smoothing technology”
The cutting edge remains smooth at all times by means of the fine grain
heat resistant Titanium compound and specialized sintering technology.
