AN5752 Aluminum Nitride Heater

Aluminium Nitride Heating Element Description

Aluminium Nitride Heating Elements are heating elements made from aluminium nitride, a material known for its exceptional thermal conductivity, electrical insulation properties, and high-temperature stability. AlN has a thermal conductivity of approximately 140-180 W/mK, which is significantly higher than that of many other ceramic materials. This allows for efficient heat transfer and uniform temperature distribution. AlN is an excellent electrical insulator with a high breakdown strength, making it ideal for applications where electrical insulation is critical. These heating elements are used in a variety of applications that require precise temperature control and efficient heat transfer.
