Thermal-management devices made from metal-matrix AlSiC (aluminum-silicon-carbide) composites have tailorable, isotropic coefficient of thermal expansions (8.75 to 11.7) and low densities (2.86 to 3.01 gm/cm3). The composites easily cast to near-net shapes with a thermal conductivity on the order of 1,000 W/mK. Devices made from the composites can also incorporate features such 5-mm-tall pin fins to improve thermal management.
