Cubic and cermet grades

Optimized performance at extreme working conditions

Cubic and cermet grades of cemented carbide from Hyperion


Cubic and cermet grades are one of the latest developments for Hyperion Materials & Technologies. This group consists of grades containing a significant proportion of g-phase (i.e., TiC, TaC, NbC, etc.) together with WC and Co.

The main features of the g-phase are good thermal stability, resistance to oxidation, and high-temperature wear. These grades are designed to provide a favorable balance of wear resistance and toughness in can tooling applications that generate high temperatures and entail close contact with ferrous materials. These conditions arise in metal cutting or high-pressure sliding contact situations involving the welding and galling of surfaces.


Applications of Cubic and cermet grades from Hyperion


Other common terms for these grades are the “can tooling”, “metal-cutting”, or “mixed-crystal” grades. In the extreme case, these grades are designed without any WC phase. Such hard metal grades are called cermets and give a unique combination of high-temperature hardness, chemical wear resistance, and low density. Cermets are traditionally avoided for wear parts because of being more brittle than standard WC-Co grades. New developments have allowed toughness to be improved significantly, and cermets are now applied in a number of demanding applications from advanced engineering components to high-performance metal sawing blades.
