As the hardest substance in nature, diamond also boasts exceptionally high thermal conductivity, reaching up to 2300 W/(m·K). This property makes it highly promising for heat dissipation applications. Copper, a common metal, not only exhibits excellent electrical conductivity but also ranks among the top metals for thermal conductivity, with a coefficient of approximately 401 W/(m·K). It also offers outstanding machinability and good toughness. By combining diamond's high hardness, thermal conductivity, and low thermal expansion coefficient with copper's high electrical conductivity, thermal conductivity, and machinability, diamond-copper composite materials have emerged, offering a range of outstanding integrated properties.
