MC-21's Rolled MMC Sheet Products
An Al-20% SiC composite material produced as rolled sheet suitable for stamping or EDM'ing of
heat spreaders, thermal planes, and other 2D parts requiring reduced coefficient of thermal
expansion and good thermal conductivity.
Al-20 vol. % SiC Sheet Properties (approximate)
- CTE: 15 ppm/°C
- Thermal conductivity: 185 W/m-K
