Stanford Advanced Material is a global supplier of high thermal Aluminum Diamond Metal Matrix Composite (Al-Diamond MMC), SAM's aluminum diamond products can be used to form large-size aluminum diamond products.
Related products: AlSiC IGBT Base Plate, Al-Si Metal Matrix Composite.
The thermal conductivity of Aluminum Diamond Metal Matrix Composite is 550 ~ 700 W/mK, which is far higher than the copper base plate and copper-molybdenum plate. It is lightweight - only 1/3 weight of the copper baseboard, and it has been tested well suited for solving the problems created by GaN’s extremely high powder density. These factors make Al-Diamond MMC an ideal thermal management material. With the further decline in the price of diamond powder, the application of aluminum diamond composites has become popular.
