Aluminium nitride machinable ceramic

AlN - Machinable ceramic

Final Advanced Materials provides machinable aluminium nitride : rods, boards or machined parts according to your drawings.

Aluminium nitride is an electrical insulating refractory material having very high thermal conductivity, higher than that of copper at 200°C, and showing high resistance to oxidation and abrasion. Unlike sintered ceramics, machining with conventional tools is possible.

This aluminum nitride has equivalent characteristics to Shapal M™ while being economically more interesting.

Aluminium nitride Ceramic applications

  • Electronic component
  • Component in low dielectric constant applications
  • Fixatures in low thermal expansion applications
