Aluminum-based silicon carbide is a particle-reinforced metal matrix composite material with aluminum alloy as the matrix and silicon carbide (SiC) particles as the reinforcement phase. It is one of the most mature and widely used advanced metal matrix composite materials in industrialization. Its core advantage lies in the ability to precisely customize thermal and mechanical properties by regulating the volume fraction of SiC, balancing structural loading and thermal management functions, and achieving "structure-function integration". It is a core key material for solving the bottlenecks of lightweight and thermal management in high-end fields such as aerospace, power semiconductors, and new energy vehicles.

Core application areas

Power semiconductors and electronic packaging

The core products are used for heat dissipation baseplates, heat sinks, packaging casings of IGBT, SiC/GaN power modules, substrates for RF devices in 5G base stations, cooling components for AI servers/data center chips, and thermal management parts for laser devices. They are the core supporting materials for the third-generation semiconductor high-power devices to address "heat dissipation anxiety" and enhance power density and service life.

New energy vehicles and rail transit

In the field of new energy vehicles: components such as motor controller housings, inverter heat dissipation substrates, battery pack heat dissipation structural components, brake discs, pistons, etc. Compared to traditional cast iron brake discs, AlSiC products reduce weight by over 50% and enhance wear resistance several times; compared to aluminum alloy housings, they improve heat dissipation efficiency by over 30% and reduce weight by over 15%.

Rail transit field: used for traction converter cooling components, braking system parts, and lightweight structural components of vehicle bodies, meeting the high reliability, long lifespan, and lightweight requirements of high-speed rail and urban rail transit.

Aerospace and defense military

aerospace fields: satellite payload brackets, phased array radar T/R module substrates, inertial navigation system structural components, spacecraft thermal control components, adaptable to extreme temperature environments in space, with large-scale applications in Chang'e series detectors and Beidou satellites.

Aviation field: Aircraft wing structural components, engine accessories, airborne electronic equipment housings, and electro-optical pod structural components, replacing traditional titanium alloy and aluminum alloy, achieving significant weight reduction while enhancing structural rigidity and high temperature resistance.

Precision optics and high-end equipment

Precision optics and high-end equipment are utilized in high-precision mirrors, lens barrels, and optical mounts. With their extremely low thermal expansion coefficient and high rigidity, they ensure the dimensional stability of optical systems under temperature changes, and are widely applied in astronomical telescopes, high-end lithography machines, and laser equipment. Additionally, they are used in wear-resistant components such as industrial robot joints, precision machine tool spindles, and high-end pumps and valves, replacing traditional alloy steel to achieve lightweight and longevity.
