Stanford Advanced Materials provides alumina nitride ceramic products with various surface finishing and metalization. Aluminum nitride is a great material for subastrates for electronics. We provide alminum niride sheets in various shapes. Polished sheets are also available.

More details

Aluminum nitride, AlN, is a light grey or white ceramic material which has a density of 3.26g/cm3. Due to its high thermal conductivity and great electrical insulation, AlN was used in microelectronic industries. Surface oxidization happened in air even for room temperature, however, the aluminum oxide layer can protect the material up to 1370 C. Metallization methods are available to allow aluminum nitride to be used in electronics applications similar to those of alumina and beryllium oxide.

The hardness of aluminum nitride ceramic is even higher than alumina, the traditional technical ceramic, making it an ideal material for applications that require good wear resistance. 

Advantage of AlN ceramic

* Very high thermal conductivity (> 170 W/mK)

* High electrical insulation capacity (>1.10^12 Ω cm)

* Strength according to the double ring method >320 MPa (biaxial strength)

* Low thermal expansion 2 to 5x10^-6 K

* Good metallization capacity
