FAQ
Are there any changes due to thermal conductivity?
Thermal conductivity is based on the amount of Co. Lower Co levels lead to higher conductivity.
Generally, higher conductivity means that heat escapes well and frictional heat can be controlled.

What is the difference between cemented carbide and cermet?
Both cemented carbide and cermet are composite materials made by mixing and sintering carbide or nitride powders with a metallic binder.
However, whereas cemented carbides are made of tungsten carbide (WC), the main component, bonded mainly with cobalt (Co) and nickel (Ni),
Cermet is made by bonding titanium compounds such as titanium carbide (TiC) and titanium carbide nitride (TiCN) with nickel (Ni) and cobalt (Co).
In other words, the difference between cemented carbide and cermet is the main component. -
What is the difference between cemented carbide and HSS?
Cemented carbide is an alloy with high hardness, heat resistance and strength. HSS, on the other hand, generally has relatively lower strength and heat resistance, but has higher impact resistance.
As their raw materials and manufacturing methods differ, there is a significant difference in costs between the two materials.
Selecting the suitable material is recommended though considering the application and the timing of replacement after installation.

What are the weaknesses of cemented carbides?
Compared to general iron alloys, cemented carbide has lower toughness, which may cause chipping or peeling of the cutting edge.
In addition, as the relative density is about twice that of iron, the heavier weight of cemented carbide may be a disadvantage.
