3. Good electrical insulation
With an electrical breakdown strength of up to 17-19 KV/mm and low dielectric losses, aluminum nitride ceramic parts provide excellent thermal management without compromising their electrical insulation, without degrading insulation properties due to heat build-up as some materials do.

4. Chemical stability
Aluminum nitride ceramic parts have excellent chemical stability, can resist chemical corrosion such as acid and alkali solutions, corrosive media, etc., and maintain long-term stable service performance.

5. Extremely high mechanical strength
Aluminum nitride ceramics have high hardness and mechanical strength, compared with alumina ceramic materials, aluminum nitride has higher bending strength, can resist mechanical stress, is not easy to deform, is wear-resistant, and is suitable for complex applications. Its flexural strength reaches 466-496MPa, ensuring the stability and durability of structural components such as ceramic ring sleeves / T-shaped short tubes under high loads.

6. Good thermal stability and Low coefficient of thermal expansion
It can be used in aerobic environments up to 1000℃, and has good thermal shock stability (ΔT400℃), and can still maintain the stability of structure and performance in environments with large temperature changes. Its coefficient of thermal expansion is 3.2-3.4×10^-6/℃, which is close to silicon, which makes it have excellent compatibility with semiconductor materials when the temperature changes, reduce the stress caused by the difference in thermal expansion, and avoid damage caused by thermal stress.

7. Precision machining
Ceramic products (such as aluminum nitride (AlN) ceramic ring sleeves, and high thermal conductivity AlN ceramic T-shaped short tubes) can be customized with precision processing to meet customers' specific size, shape, surface finish and other requirements, ensuring the accuracy and reliability of the overall equipment, such as: the diameter accuracy of the ring sleeve, the inner and outer diameter accuracy of the T-shaped short tube, etc.
