MMC Die-Cast
Joint development of high-pressure precision casting technology (die-casting) using "MMC"(Metal Matrix Composites) which is a composite material of metal and ceramics is conducted at JAPAN FINE CERAMICS CO., LTD. and KEISHIN Co., Ltd.
Features
It is a composite material that realized better physical properties by combining base metal (aluminum) and ceramic reinforcement (SiC: silicon carbide). SiC particles are dispersed in aluminum alloy.
- Lightweight and High rigidity
(With a density equivalentto aluminum , and the rigidity is 1.6 times.) - Low thermal expansion (Lower than copper)
- High thermal conductivity (1.4times of Die-Cast product)
- Vibration damping properties
