Polycrystalline CVD diamond heat sink materials
CVD (Chemical Vapor Deposition) polycrystalline diamond is a diamond material made by vapor deposition and contains multiple grains. Unlike single crystal diamond, polycrystalline diamond is composed of many small grains forming a polycrystalline body. This material has excellent thermal conductivity, high hardness and wear resistance, making it ideal for efficient heat dissipation applications in electronic and optoelectronic devices.
Features of polycrystalline CVD diamond heat sink materials
High thermal conductivity: The thermal conductivity of polycrystalline diamond typically ranges from 1000 to 1500 W/m·K, which, while slightly lower than single-crystal diamond, is still significantly higher than traditional heat sink materials such as copper and aluminum.
Chemical stability: Polycrystalline diamond is highly resistant to most chemical agents, making it suitable for applications in harsh environments.
Electrical insulation: It is an excellent electrical insulator, preventing electrical shorts and electrical interference.

In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
