Shapal M™ machinable ceramic
Final Advanced Materials provides Shapal M™ machinable aluminium nitride : rods, boards or machined parts according to your drawings.
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.
Shapal M™ Ceramic applications
- Electronic component
- Component in low dielectric constant applications
- Fixatures in low thermal expansion applications
