MMC stands for Metal Matrix Composites, and this material has both properties of ceramics and metals. There are several varieties of MMC. Top Seiko has extensive experience in machining Si-SiC and Al-SiC. This material has advantages in thermal conductivity, thermal expansion, machinability, and so on. Also, MMCs are available in large sizes.
We also handle precision machining of Ceramic Matrix Composites (CMCs). Due to non-disclosure requirements, we cannot introduce further information.
