Product Details
Diamond copper is a composite material of diamond powder and copper alloy. Using high-quality synthetic diamond powder, which has a thermal conductivity of about 1000 W/M.K, and a very low thermal expansion coefficient, under the appropriate process, diamond particles and copper alloy to reach a metallurgical bonding interface, the diamond copper composite material has excellent thermal conductivity and appropriate thermal expansion coefficient.
Diamond aluminum, similar to diamond copper, has a lower density, but slightly inferior thermal conductivity to diamond copper.
