Performance Comparison
| Unit | Alumina |
Zirconia
| Silicon carbide | Silicon nitride | Tungsten carbide | Titanium based metal ceramics |
Density | g/cm³ | 3.7-3.9 | 5.35-6.0 | 2.65-3.15 | 2.4-2.5 | 13.5-15 | 6.2-7.9 |
Hardness | HRA | 85-93 | 85-91 | 87-95 | 89-95 | 93Max | 86-95 |
Bending Strength | Mpa | 280-360 | 900-1150 | 150-550 | 165-200 | 1500-3200 | 1200-3000 |
Low density: The density is only about 50% of tungsten cobalt hard alloy, and the quantity of products per unit weight is twice that of tungsten cobalt hard alloy.
High strength: The bending strength is comparable to tungsten carbide.
Energy saving: The weight of products with the same quantity is significantly reduced, which lowers the energy consumption of equipment operation.
