Shapal™ M soft Machinable Aluminum Nitride Sheet

Shapal™ M soft Machinable Aluminum Nitride Sheet provides a flat, easily processed ceramic for heat‑spreading and insulation duties across compact assemblies. It routes and drills with standard tools, so custom cutouts, slots, and mounting features are straightforward to execute. Engineers use it as a clean, stable plate in vacuum builds, power modules, and precision fixtures that see temperature changes and demand low outgassing. The material conducts heat while electrically isolating, helping systems stay cool without compromising safety or sensor fidelity. Compared with common machinable glass‑ceramics, it brings higher thermal performance for thinner, lighter plates. Typical uses include backer plates, masks, carrier panels, and spacers that must remain flat and dimensionally consistent. For R&D and production lines, Shapal M sheet enables quick, precise ceramic panels that perform reliably in harsh, clean, or high‑vacuum environments.
