Aluminium Nitride - Sintered ceramic

Aluminium nitride shows remarkably high thermal conductivity, together with good electrical insulating properties, making this material a useful resource for electrical engineering projects. In addition, this material can be metal-plated by conventional processes, in preparation for brazing or welding. Aluminum Nitride (AlN) Ceramics Advanced Ceramics Aluminum Nitride Ceramic Properties. -Very high thermal conductivity (> 170 W/mK) -High electrical insulation capacity (>1.1012cm), withstand voltage strength. -Low dielectric constant and low dielectric loss. -Low thermal expansion 4 to 6×10-6K-1 (between 20 and 1000°C) -Good metallization capacity. -Expansion coefficient can be matched

Aluminum nitride as an alternative ceramic for fabrication

Jun 01, 2020 · Aluminum nitride (AlN) as a family of advanced ceramics, offers significant thermal conductivities. The high the thermal conductivity, the more uniform temperature distribution. Higher thermal conductivity of the AlN decreases the danger of undesirable thermal gradients, and consequently the material fracture.
