Fabriion of CuSiC metal matrix composites | SpringerLink
A CuSiC MMC heatspreader will offer high thermal conductivity between 250 and 325 W/mK and corresponding adjustable thermal expansion coefficient between 8.0 and 12.5 ppm/ C. The primary challenge of CuSiC manufacture was to prevent reaction between copper and silicon carbide during high temperature densifiion, which dramatically degraded the thermal conductivity.
