Aluminum Nitride (AlN)

Aluminum nitride substrates are used in microelectronics applications for medium to high power circuits requiring extremely good thermal conductivity 170 W/mK along with excellent mechanical and electrical properties. Being non-toxic they are finding increasing application in replacing beryllium oxide substrates which have inherent toxic properties.
Notice: All International Aluminum Nitride (AlN) orders are under International Traffic in Arms Regulations (ITAR) and Export Administration Regulations (EAR). Please call us at 508.865.1668, or email us at websales@stellarind.com.
