About Aluminum Nitride Ceramics

Aluminum Nitride (AlN) Ceramic is an excellent material to use if high thermal conductivity and electrical insulation properties are required; making it an ideal material for use in thermal management and electrical applications.

Additionally, Aluminum Nitride Ceramic is common alternative to Beryllium Oxide (BeO) in the semiconductor industry as it is not a health hazard when machined.

Aluminum Nitride Ceramic has a coefficient of thermal expansion and electrical insulation properties that closely matches that of Silicon Wafer material, making it an useful material for electronics applications where high temperatures and heat dissipation is often a problem.

Aluminum Nitride Ceramic commonly comes in substrates up to 1 mm thick which can easily be laser cut. It can also come in thicker forms.
