Aluminum Nitride (AlN) combines high thermal conductivity with strong electrical resistance, making AlN an excellent solution for many electronic applications. Unlike most electrically insulative materials which are often also thermally insulative. AlN allows electrical systems to dissipate heat quickly in order to maintain maximum efficiency.
There are two kinds of AIN due to different production methods, one is direct sintered AlN, another is hot pressed AIN, and their color is different, traditional color is grey, and hot-pressed AIN is black.
Aluminum Nitride Advantages:
- High heat dissipation with thermal conductivity of 170 W/mK
- Non-toxic alternative to BeO
- Thermal expansion coefficient similar to Si, GaN, and GaAs semiconductors
- High dielectric strength
