Aluminum nitride (AlN) 

Aluminium Nitride is one of the few materials that offer electrical insulation and high thermal conductivity. This makes AlN very useful for high power electronic applications in heat sinks and heatsink applications.

Aluminium Nitride (AlN) is an excellent material if high thermal conductivity and electrical insulation properties are required. Because of its qualities, it is an ideal material for thermal management and electrical applications.

Some common applications for Aluminium Nitride include the following: Heat Sinks & Heat Sinks Electrical Insulators for Lasers Chucks, Clamping Rings for Semiconductor Processing Equipment Electrical Insulators Silicon Wafer Handling & Processing Substrates & Microelectronics Insulators & Optoelectronics Electronic Packaging Substrates Chip Carriers for Sensors & Detectors Chip Lets Col let Lasers for Thermal Management Assemblies Molten Metal Fixtures Microwave Device Packaging

Aluminum Nitride Tube Applications

-Heat-resistant punching and heat exchange materials

-Heat-resistant materials

- Microwave attenuation materials

AlN ceramic materials have broad application prospects and broad potential markets in the electronic field, electric power, locomotive, aviation and aerospace, national defense and military industry, communication, and many industrial fields.
