The Aluminum Nitride (ALN) ceramic has high thermal conductivity (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 coefficient is similar with Si, which is widely used in communication component, high power led, power electronic devices and other fields. Special spec products can be produced upon requests.We can also customize it according to your requirements.
We can supply all kinds of ALN ceramic products. Such as ceramic substrate, rod, pats, etc.
