Aluminum nitride toxicity non-toxic
With high thermal conductivity , good metalization capacity , high electrical insulation capacity , Low thermal expansion, high temperature and corrosion resistance.
It is one of the best materials to use if high thermal conductivity is required.
Aluminium Nitride ceramic
Aluminum nitride (AlN) is a newer material in the technical ceramics family which
features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. This unusual combination of properties makes AlN a critical advance materials for many applications.
This material is of interest as a non-toxic alternative to beryllia.
