Aluminum Nitride(AlN) combine high thermal conductivity with strong electrical resistance, making AlN an excellent solution for many electronic applications. Unlike many electronically insulative materials-which are often also thermally insulative. AlN allows electrical systems to dissipate heat quickly in order to maintain maximum efficiency.
