Product type
Alumina ceramic is a high-performance material made primarily from aluminum oxide (Al2O3). It is known for its exceptional hardness, wear resistance, and thermal stability, making it suitable for a variety of industrial applications. Alumina ceramics are typically produced through processes such as sintering and can be found in various forms, including tiles, rods, and custom shapes.
| Composition | Aluminum oxide (Al2O3) content typically 85% to 99% |
| Hardness | Mohs hardness of 8 to 9 |
| Density | 3.5 to 4.0 g/cm³ |
| Temperature Resistance | Up to 1600°C (2912°F) |
| Electrical Resistivity | High, typically >10^12 ohm-cm |
| Typical Forms | Tiles, rods, tubes, and custom shapes |
When selecting alumina ceramic, consider the specific application requirements such as hardness, temperature resistance, and form. Specify the desired aluminum oxide content, dimensions, and any required tolerances. It's also important to inquire about certifications that may be relevant to your industry, such as ISO standards, and to determine the quantity needed for your project to ensure cost-effective pricing.
