Excellent properties and wide applications of diamond/Cu composites

Diamond/Cu composites, as a new type of material that combines the excellent thermophysical 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 uses a specific preparation process to evenly disperse diamond particles in the copper matrix, thereby achieving complementary and improved performance.

Excellent Performance

High Thermal Conductivity：

As one of the materials with the highest thermal conductivity in nature, diamond can significantly increase the overall thermal conductivity of the composite material when combined with copper. This property gives diamond/Cu composites significant advantages in the field of heat dissipation, especially in heat dissipation solutions for high-power electronic components.

Low Coefficient of Thermal Expansion:

Diamond has an extremely low coefficient of thermal expansion, which offers significant advantages over metals such as copper. Diamond/Cu composite materials can control the thermal expansion coefficient of the composite material by adjusting the ratio of diamond to copper to match the needs of different application scenarios, thereby reducing thermal stress caused by temperature changes.

Excellent Mechanical Properties:

The high hardness and strength of diamond endow diamond/Cu composites with excellent wear resistance, impact resistance and fatigue resistance. These properties make the composites have a wide range of application potentials in situations that need to withstand high loads and wear.

Good Electrical Conductivity:

Although diamond itself is an electrical insulator, copper as a matrix material ensures that the diamond/Cu composite material still has good electrical conductivity. This gives the composite material a unique advantage in situations where both thermal conductivity and electrical conductivity need to be considered (such as certain electronic devices).

Widely Used
