Aluminum Nitride

Applied Ceramics fabricates Aluminum Nitride (AIN) into common forms and finely machined parts for a variety of precision electronic applications.

Aluminum Nitride is a versatile material most often used in situations that demand both high thermal conductivity and electrical insulation. This unique ability, combined with its low toxicity, makes AIN ideal for managing rapid heating and removal of heat from other components and systems, such as in heat sinks and spreaders.

In addition, its low coefficient of thermal expansion, which is similar to silicon material, means AIN is a trusted substance for use in semiconductor products. The material remains highly stable through a wide range of temperatures.

In high-power electronic applications, components such as solid state transistors can generate significant amounts of heat, affecting performance. A substrate made from AIN can draw away the heat while being an insulator for mounted components. Similarly, LED applications produce high levels of heat. A traditional heat sink along with an AIN substrate can dissipate heat and improve performance.

Applied Ceramics has extensive experience in aluminum nitride machining and can create blocks, sheets and bars. We have the practical knowledge needed to machine AIN into fine rings and other custom parts to meet tight tolerances and specifications. Our refined machining processes enable Applied Ceramics to drill, grind or thread Aluminum Nitride with great accuracy and repeatability.
