Frequently Asked Questions

Is SHAPAL produced in Japan?

Yes. SHAPAL™ machinable ceramics—including SHAPAL Hi-M—are produced in Japan by Tokuyama Corporation. They are well-known for their high thermal conductivity and excellent dimensional stability.

What is SHAPAL Hi-M?

SHAPAL Hi-M is a premium AlN–BN composite machinable ceramic that offers:

High thermal conductivity
Excellent electrical insulation
Good machinability using carbide or diamond tools
Stable performance from cryogenic to high-temperature environments
It is often selected for semiconductor, laser, aerospace, and precision fixture components.

Where can SHAPAL be machined?

SHAPAL requires professional ceramic machining using diamond or carbide tools.
Jundro Ceramics is one of the experienced suppliers capable of machining SHAPAL with tight tolerances, small-batch prototyping, and complex geometries. We provide full QC inspection, material traceability, and precision milling for SHAPAL components.

SHAPAL vs. AlN — which has higher thermal conductivity?

SHAPAL has moderate thermal conductivity (typically 70–90 W/m·K), while sintered Aluminum Nitride (AlN) reaches 170–180 W/m·K.
Conclusion: AlN has significantly higher thermal conductivity; SHAPAL is chosen when a balance of machinability + thermal performance is required.

Can SHAPAL parts be custom-machined?

Yes. SHAPAL can be fully customized—including milling, turning, drilling, threading, and polishing—without sintering after machining. It supports small-batch and prototype fabrication, making it ideal for R&D, semiconductor tools, fixtures, and precision thermal components.
