CIM Materials
CIM metarials uses a wide range of ceramic powders, including alumina, zirconia, silicon nitride, and silicon carbide, which are mixed with a binder and then injected into a mold, followed by debinding and sintering to create complex ceramic parts.
Here’s a more detailed look at common materials used in ceramic injection molding:
CIM Metarials Alumina (Al₂O₃)
- Widely used due to its high wear and corrosion resistance, electrical insulation properties, and mechanical strength.
- Available in various grades (e.g., 92%, 96%, 99.7%) for different applications.
- Suitable for applications like electrically insulating bodies, chemical operations, industrial machinery, and vacuum industry.
CIM Metarials Zirconia (ZrO₂)
- Known for its high strength, toughness, and damage tolerance.
- Used in medical and dental applications, as well as other applications requiring high strength and wear resistance.
| Material | Collor | Density (g/cm³) | Hardness (HV10) | Flexural strength/Mpa | Fracture toughness (Mpa/m1/2) | Relative permittivity | Thermal conductivity (W/m·K) | High temperature resistant (emp./℃) |
| ZrO2 | Customizable | 5.9~6.1 | 1150~1400 | 700~1300 | 5~15 | 25~35 | 2~8 | 1000 |
| 95# Al2O3 | Customizable | 3.4~3.6 | 1600~1800 | 300~400 | 2~4 | 8~10 | 18~25 | 1500 |
| 99# Al2O3 | Customizable | 3.7~4.0 | 1800~2100 | 350~450 | 2~4 | 8~10 | 25~35 | 1600 |
Toughened Alumina (ZTA)
- Combines the strength of zirconia with the wear resistance of alumina.
- Suitable for applications requiring both high strength and good surface quality.
Silicon Nitride (Si₃N₄)
Offers high strength, high-temperature strength, and thermal shock resistance.
Silicon Carbide (SiC)
Known for its high hardness, wear resistance, and high-temperature capabilities.
Other CIM Metarials
- ATZ (Alumina-Titanium Zirconium)
- Electrostatic Discharge (ESD) materials
- Aluminum nitride (AlN)
- High-purity oxides and carbides, such as WC and SiC
