Aluminium Nitride – Fully Sintered and Machinable
Aluminium Nitride is a specialist material for the most demanding applications.
Aluminium Nitride has the highest thermal conductivity of any ceramic material (on par with most metals), as well as extremely good electrical insulation. This makes it the top-of-the-range choice for the most demanding of heat sink applications.
It is stable up to 1000 °C / 1800 °F in air and 1900 °C / 3450 °F in inert atmospheres. The thermal expansion coefficient is lower than that of common heat sink materials such as aluminium and alumina. The thermal expansion coefficient is a close match to the expansion of common semiconductor substrate materials, making it ideal for the mounting of large semiconductor devices.
Aluminium Nitride is the very best ceramic commercially available for heat sink applications. It is often used in microelectronics, lighting, power, optics and the ever growing field of renewable energy.
IPS Ceramics offers the following two grades:
- Machinable – for excellent thermal conductivity of 90 W/mK
- Fully-sintered – for exceptional thermal conductivity of 170 W/mK
