Core Material & Manufacturing Advantages
- Base Material: High-purity alumina powder (purity 95%–99.9%) is the main raw material, with higher purity enhancing performance in thermal conductivity and stability.
-
- Production Processes: Adopts dry pressing, injection molding, or tape casting, followed by sintering at 1500–1800℃ and precision grinding, ensuring dense structure and dimensional accuracy.
-
- Customization Capability: Can be tailored for shape (circular, square, special-shaped), size (micro to large specifications), and surface treatment (metallization, polishing) to match equipment assembly needs.
