Design Features

Aluminum nitride ceramic discs, also known as precision-drilled ceramic rings, fully utilize the physical and chemical properties of 

aluminum nitride (AlN), providing an ideal material choice for various high-end applications:

High Thermal Conductivity and Electrical Insulation

Aluminum nitride boasts a thermal conductivity of up to 170 W/m·K, combined with a breakdown strength of 17-19 KV/mm, 

making these discs highly effective in applications requiring rapid heat dissipation while maintaining electrical insulation.

Precise Drilling and Shape Design

The disc design incorporates precise drilling for assembly and fixation, enhancing performance in heat dissipation applications 

and allowing gas or liquid flow for optimized thermal management.

Low Coefficient of Thermal Expansion

With a coefficient of thermal expansion of 3.2-3.4 × 10⁻⁶/ºC, similar to some metals and semiconductors, this helps reduce 

mechanical stress caused by temperature changes.

Excellent Physical Stability

With operating temperatures up to 1000°C and thermal shock resistance up to 400°C, these discs maintain stable performance 

at high temperatures.

Smooth Surface and Uniform Grayish-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.

Application areas

Aluminum nitride ceramic discs play a key role in multiple technological fields, especially in high-performance equipment:

Heat Dissipation for Electronic Devices

Used in power semiconductors, power LEDs, and high-performance computing devices, which require effective heat 

dissipation to maintain performance and extend lifespan.

Electrical Insulation and Structural Support
