Details

Aluminum nitride belongs to the diamond-like nitride, hexagonal crystal system, and wurtzite type crystal structure. It is non-toxic and appears white or grayish white. AlN can be stabilized up to 2200 ℃. Flexural strength under room temperature is high, and decreases slowly with the increase of temperature. Good thermal conductivity, low coefficient of thermal expansion, making it a good heat-resistant impact material.

Characteristics:

1. High thermal conductivity and high voltage insulation
2. High temperature and moisture resistance
3. Good mechanical performance and high bending strength
4. Low dielectric constant, effectively resistant to electronic signal interference

Typical applications:

1. Opto electronic communication equipment
2. High frequency microwave application device
3. Automotive electronic modules
4. Application of Aerospace Military Electronics
5. LED/high-power module
6. Heat dissipation components for electronic products
