Metal-Based Composite Materials

MMC(Ai/SiC composite material)
We provide metal composite materials such as Metal Matrix Composites (Al/SiC) and spacers, substrates, housings, etc., mainly composed of Cu-Mo.

Spacer

Introduction
Double-sided cooling technology is a new structural technology for recent power module products. It effectively reduces the parasitic inductance and parasitic resistance of the device, thereby effectively improving the power density and reliability of the device.
This product serves as an essential primary material for devices such as double-sided cooling devices, mainly playing the roles of 'heat conduction', 'electrical conduction', and 'support'.
Application Field
Spacer-related products are applied in fields such as new energy vehicles, power electronics, and smart grids.
