Al–SiC Metal Matrix Composite (MMC) Baseplate

With the rapid growth of electric vehicles (EV/HEV), industrial power electronics, and renewable energy systems, thermal performance and reliability are critical to power module design. Al–SiC (Aluminum–Silicon Carbide) MMC baseplates are widely adopted by Tier-1 manufacturers for their excellent thermal management and structural stability.

Al–SiC combines an aluminum matrix with silicon carbide (SiC) reinforcement. By adjusting the SiC content, the material achieves a balanced combination of high thermal conductivity, controlled CTE, high stiffness, and lightweight characteristics, making it ideal for high-power module applications.

Nexteck supplies high-quality Al–SiC baseplates for automotive and industrial power modules, supporting efficient heat dissipation, improved reliability, and long service life.
