Aluminum Nitride Ring
Aluminum Nitride Ring is made from high-purity aluminum nitride ceramic, possessing exceptional thermal conductivity (170-230 W/m·K), excellent electrical insulation, and high-temperature resistance (up to over 1000℃). Advanced Ceramics Hub can supply customized solutions in diameter, thickness, and surface finish to meet diverse industrial and research requirements.
Aluminum Nitride Ring Advantages
- High thermal conductivity (170-230 W/mK), up to 9.5 times that of alumina.
- A thermal expansion coefficient similar to that of silicon (Si).
- Superior electrical insulation and lower dielectric constant.
- Higher mechanical strength (450 MPa).
- Excellent resistance to molten metal corrosion.
- High purity and non-toxic.
Aluminum Nitride Ring Applications
- Electronics: With high thermal conductivity and electrical insulation, they are used in heat-dissipating substrates, packaging, and insulating rings in high-power devices like LEDs, power modules, and microwave components.
- Semiconductors: In semiconductor manufacturing, they serve as support or insulating components in high-temperature environments due to their heat resistance and corrosion resistance.
- Mechanical: AlN rings’ high hardness and wear resistance make them ideal for wear-resistant parts and sealing rings in demanding mechanical conditions.
- Aerospace: Their lightweight, high-strength, and heat-resistant properties make them suitable for high-temperature components in aerospace applications.

Aluminum Nitride Ceramic Machining
Aluminum Nitride (AlN) ceramic machining is a precise process used to fabricate high-performance components from aluminum nitride materials. Machining aluminum nitride ceramics requires specialized equipment and techniques to handle their brittleness and hardness. Proper tooling and controlled environments are essential to avoid material damage and achieve the desired surface finish and dimensional accuracy. The common machining methods are as follows:
- Diamond Cutting: Diamond tools are used to achieve fine precision and smooth surface finishes, ideal for complex shapes.
- Laser Cutting: A non-contact method used for intricate shapes, with high precision and minimal thermal impact.
- Precision Grinding: Utilized to achieve fine tolerances and surface finishes. Requires special care to prevent cracking or chipping due to the ceramic’s brittleness.
- Wire EDM (Electrical Discharge Machining): A method often used for intricate cutting, especially for thin and complex geometries.
Aluminum Nitride Ceramic Packaging
Aluminum Nitride Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
