Excellent electronic material Aluminum Nitride parts Ring Ceramic Insulation
Product Description
The Aluminum Nitride(AlN) ceramic has high thermal coductivity(5-10 times as the Alumina ceramic), low dielectric constant and dissipation factor, good insulation and excellent mechanical properties, non-toxic, high thermal resistance, chemical resistance, and the linear expansion cofficient is similar with Si, which is widely used in communication compents, high power led, power electronic devices and other fields. Special spec products can be produced upon requests.
