Global Diamond-SiC Composite Material Market Strategic Research Report

Scope of the Report

The global Diamond-SiC Composite Material market size is predicted to grow from US$ 27.39 million in 2025 to US$ 237 million in 2032; it is expected to grow at a CAGR of 36.3% from 2026 to 2032.

In 2025, global sales volume of Diamond-SiC Composite Material was approximately 3.5 tons, with a global average selling price of about USD 8,000/kg. The gross margin of major manufacturers was generally around 35%–55%.

Diamond-SiC Composite Material is a high-thermal-conductivity composite material designed for thermal management in high-power chips and advanced packaging. It is mainly composed of a high-thermal-conductivity diamond phase and a silicon carbide ceramic matrix. The material combines the extremely high thermal conductivity of diamond with the high strength, high-temperature resistance, corrosion resistance and thermal stability of silicon carbide, enabling rapid heat conduction and spreading under high-heat-flux conditions while reducing localized hotspots and thermal stress concentration in devices. Compared with traditional copper, aluminum, tungsten-copper, molybdenum-copper and conventional ceramic thermal management materials, Diamond-SiC Composite Material offers stronger advantages in thermal conductivity, thermal expansion matching, dimensional stability and high-temperature reliability, making it particularly suitable for addressing the “high heat generation, limited space and strict matching” challenges in high-computing-power chips, high-power semiconductors and RF devices.In China, Huanghe Whirlwind has made certain technical progress in diamond-SiC composite material. Public information indicates that its related materials have achieved thermal conductivity of over 700 W/(m·K) and a coefficient of thermal expansion as low as 2.6 ppm/°C, providing a technical foundation for expansion into high-end semiconductor thermal management materials. However, in terms of commercialization progress, the product still appears to be mainly at the R&D validation and industrialization promotion stage, with no clear evidence of large-scale mass production or stable commercial supply. It is expected to become a potential new growth area in high-end semiconductor materials.

The downstream applications of Diamond-SiC Composite Material mainly include AI and data centers, communication and RF, automotive electrification, power and energy, semiconductor lasers, aerospace and other high-end electronic equipment fields. Among these, AI and data centers represent the most promising growth area at present. As the power consumption of AI computing chips continues to rise, heat flux density in advanced packaging increases, and SiC/GaN power devices see accelerated adoption, traditional metal and conventional ceramic materials are facing greater pressure in terms of thermal conductivity, thermal expansion matching and packaging reliability. Diamond-SiC Composite Material is therefore expected to become an important development direction for high-end thermal management materials.
