Cermet (metal ceramics) and Cemented Carbide are both high-hardness materials produced through powder metallurgy processes, and are commonly used in cutting tools and wear-resistant parts. However, their compositions, properties, and application focuses are different. Here is a clearer comparison:
1. Difference in material composition
| Item | Cermet | Cemented Carbide |
| Main hard phase | TiC、TiN、TiCN | WC |
| Metallic bonding phase | Ni、Co、Mo | CO |
Material characteristics | High proportion of ceramic components | Slightly higher proportion of metals |
Simple explanation:
Metal ceramics = Titanium-based ceramics + Metal binder
Cemented = tungsten carbide + cobalt
2. performance comparison
| Performance | Cermet | Cemented Carbide |
| Hardness | very high | high |
| Toughness | lower | Better |
| Abrasive resistance | very good | good |
| Resistance to oxidation | good | ordinary |
| Anti-chipping | ordinary | better |
Surface smoothness | better | ordinary |
Simple explanation:
Metal ceramics: Hard, wear-resistant, with good surface quality
Cemented: More sturdy and less prone to breakage
3. Difference in cutting performance
| Item | Cermet | Cemented Carbide |
| Cutting Speed | high speed | medium-high speed |
| Finisghing | very good | good |
| Roughing | not suitable | suitable |
impact resistance | not | high |
Finishing processing, semi-finishing processing → Metal ceramics are even better
Coarse processing, intermittent cutting → Better with cemented carbide
4. Typical application
Metal ceramic often used for:
Precision-cutting blade
CNC turning tools
Stainless steel processing
High-speed cutting
Features: Smooth processing surface, long wear resistance life.
Cemented carbide often used for
Milling bit
Drill bit
Heavy-duty cutting tools
Mold
Features: High strength, adaptable to vario
