Machinable Ceramics
Shapal is a machinable form of Aluminium Nitride ceramic with excellent mechanical strength and thermal conductivity. Shapal has unique characteristics. It is suitable for a wide range of applications, particularly in the vacuum and nuclear industries. Shapal has zero porosity, good abilities to seal under vacuum, low thermal expansion coupled with a high heat resistance. Shapal also offers excellent machinability with conventional machine tools.
