Aluminum nitride ceramic sealing ring-gaskets
Alias: precision perforated ceramic ring piece parts
Description：
Sealing ring-gaskets made of aluminum nitride (AlN) ceramics, also known as precision perforated ceramic ring piece parts. These aluminum nitride ceramic pieces feature precise hole punching and specific shape designs, allowing them to act as mechanical supports, electrically insulating components, or thermal interface materials in various precision applications. The porous design can be used not only for assembly and fixation, but also for improving heat dissipation efficiency, allowing gas or liquid to flow through these holes, thereby improving the overall thermal management performance of the equipment.
Features:
Aluminum nitride ceramic sealing ring-gaskets (Alias: precision perforated ceramic ring piece parts) take full advantage of the physical and chemical properties of aluminum nitride (AlN), providing an ideal material choice for a variety of high-end applications:
1. High thermal conductivity and electrical insulation
Aluminum nitride has a thermal conductivity of up to 170 W/(m·K), combined with an electrical breakdown strength of 17-19 KV/mm, which makes these ring-pieces highly effective in applications that require rapid heat dissipation while maintaining electrical insulation.
2. Precise punching and shape design
The ring-piece design includes precise punch hole positions for assembly and fixation while enhancing its performance in thermal applications, allowing gas or liquid flow and optimizing thermal management.
3. Low coefficient of thermal expansion
The coefficient of thermal expansion is 3.2-3.4×10-6/°C, which is similar to that of certain metals and semiconductor materials, helping to reduce mechanical stress due to temperature changes.
4. Excellent physical stability
The maximum operating temperature is up to 1000℃, combined with their thermal shock stability (ΔT400℃), which allows these ring-pieces to maintain stable performance in high-temperature environments.
5. Smooth surface and Uniform off-white tone
This not only reflects the high purity and uniformity of the material but also helps reduce friction and increase contact efficiency, optimizing performance.
Applications:
Aluminum nitride ceramic ring-pieces play a pivotal role in several technical areas, particularly in high-performance equipment:
1. Heat dissipation of electronic devices
Used in power semiconductors, power LEDs, and high-performance computing devices that require efficient heat dissipation to maintain performance and extend life.
2. Electrical insulation and structural support
Used in electronic assemblies to provide mechanical support to circuits while maintaining necessary electrical insulation, especially in high-temperature or variable environments.
3. Chemical and medical equipment
Due to its chemical stability and high-temperature resistance, it is suitable for chemical processing and medical devices to withstand rigorous sterilization and cleaning processes.
4. Precision mechanical and optical equipment
Used in equipment that requires high precision and thermal stability, such as laser systems and high-end optical equipment.
With their high thermal conductivity, electrical insulation, mechanical stability, and chemical stability, aluminum nitride ceramic ring-pieces provide efficient and reliable solutions in modern high-tech applications. The design and performance optimization of these ring-pieces allow them to perform well in high-temperature, high-voltage and demanding electrical insulation applications, meeting the stringent requirements of electronics manufacturing, energy technology and advanced material handling. Through their exceptional physical and chemical properties, aluminum nitride ceramic ring-pieces ensure long-term stable operation of equipment under demanding operating conditions, making them irreplaceable critical components in many high-end applications.
