Product Description

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 components, high power led, power electronic devices and other
fields.Special spec products can be produced upon requests.

Product Performance:
- High thermal conductivity, high flexural strength, high temperature
- Good electrical insulation
- Low dielectric constant and loss
- Able to be laser drilled, metallized, plated and brazed

Product Features:
1.Uniform microstructure
2.High thermal conductivity* (70-180 Wm-1K-1), tailored via processing conditions and additives
3.High electrical resistivity
4.Thermal expansion coefficient close to that of Silicon
5.Resistance to corrosion and erosion
6.Excellent thermal shock resistance
7.Chemically stable up to 980°C in H2 and CO2 atmospheres, and in air up to 1380°C (surface oxidation
occurs around 780°C; the surface layer protects the bulk up to 1380°C).
