While ceramic materials generally have numerous advantages that are not found in metals or high polymer materials, they are difficult to process because of their hardness and fragility. For that reason, they posses both merits and demerits. In comparison to these conventional ceramics, Tokuyama's machinable aluminum nitride ceramics exhibit excellent machinability and strength, enabling them to be used in a wide array of fields, including as structural materials.
Because SHAPAL™ Hi M-soft exhibits excellent machinability, it is often used to make prototypes for mass-produced items.
The unique features of SHAPAL™ Hi M-soft also make it an excellent material for the following applications:
・Various electrical components that require heat dissipation and electrical insulation
・Tools, setters, and other items that require a low coefficient of thermal expansion
・Various components that require high-frequency wave properties, including low dielectric constant and dielectric loss
・Crucibles for vapor deposition
・Specialized furnace components, including insulators and protective tubes
・Other applications in a wide range of fields, including structural materials
・Features that facilitates machinability
As shown in the photo at left, taken with a scanning electron microscope, SHAPAL™ Hi M-soft contains lamellar crystal particles that prevent surface cracks caused by carbide cutting tools from going deeper inside.
