Copper/diamond composite material is an isotropic, high thermal conductivity, low thermal expansion coefficient lightweight thermal conductive composite material. Its organizational structure consists of diamond powder and copper matrix made under high temperature and high pressure. Diamond copper composite material is suitable for chip packaging substrates, with high thermal conductivity and a thermal expansion coefficient that matches the chip. Its performance can be adjusted in a wide range to meet the needs of chip packaging.

Copper/diamond composite materials, as a new type of material that combines the excellent thermal and physical properties of diamond with the excellent electrical, thermal, and processing properties of copper, have attracted widespread attention in the field of materials science in recent years. This composite material achieves complementary and improved performance by uniformly dispersing diamond particles in a copper matrix through specific preparation processes. Diamond, as one of the materials with the highest thermal conductivity in nature, can significantly enhance the overall thermal conductivity of composite materials when combined with copper. This characteristic gives diamond/copper composite materials significant advantages in the field of heat dissipation, especially in heat dissipation solutions for high-power electronic components. Diamond has an extremely low coefficient of thermal expansion, which gives it significant advantages over metals such as copper. By adjusting the ratio of diamond to copper, the thermal expansion coefficient of diamond/copper composite materials can be controlled to match the needs of different application scenarios, thereby reducing thermal stress caused by temperature changes. The high hardness and strength of diamond endow diamond/copper composite materials with excellent wear resistance, impact resistance, and fatigue resistance. These characteristics make composite materials have broad application potential in situations where high loads and wear are required. Although diamond itself is an electrical insulator, copper as the matrix material ensures that diamond/copper composite materials still have good electrical conductivity. This gives composite materials unique advantages in situations where both thermal and electrical conductivity need to be considered simultaneously, such as in certain electronic devices. Copper/diamond composite materials have shown wide application potential in multiple fields due to their unique high thermal conductivity, low thermal expansion coefficient, high hardness, and wear resistance. In the field of electronic packaging, it has become an ideal choice for high-power electronic components, effectively improving heat dissipation efficiency and equipment stability; As a thermal interface material, it improves the efficiency of heat transfer; In the manufacturing of cutting tools and molds, it improves machining accuracy and efficiency while reducing costs; The aerospace industry has utilized its lightweight, high-strength, and high thermal conductivity characteristics to enhance the performance and safety of aircraft; In the field of energy, this material is also considered an important candidate material for improving heat exchange and solar energy conversion efficiency.
