Shapal M Aluminium nitride : Machinable ceramic


Final Advanced Materials provides shapal M machinable aluminium nitride : Rods, boards or machined parts according to your drawings



Shapal M - Aluminium nitride presentation

It 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 ceramic is available in bars (maxi D.58x300mm), in plates (maxi 315x200x60mm) or in parts machined by ourselves according to plans.
