Aluminum Nitride (AlN) is a unique ceramic that combines high thermal conductivity with electrical insulation, making it ideal for CNC machining in electronics, optoelectronics, and heat management systems. Its performance in thermal cycling and dielectric strength sets it apart among technical ceramics.
Aluminum Nitride (AlN) is a covalently bonded ceramic composed of aluminum and nitrogen. It is best known for its remarkable thermal conductivity, second only to diamond among ceramics, while also being a strong electrical insulator. This combination makes it highly suitable for thermal interface components and advanced electronic packaging.
We offer CNC machining for high-purity sintered AlN with tight tolerances and consistent quality.
