Aluminum Nitride Custom Machined Parts Description

Alumina nitride custom-machined parts are made of high-purity aluminum nitride ceramics. AlN is a light grey or white ceramic material that 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 the air even at room temperature, however, the 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 AlN custom machined parts is even higher than alumina, the traditional technical ceramic, making it an ideal material for applications that require good wear resistance.
