Product Brief Introduction
MoCu alloy is similar with Tungsten copper alloy,its thermal expansion coefficient and thermal conductivity can be adjusted to match many different materials,it has lower density,but its CTE is higher than WCu

MoCu alloy products are widely used in applications,such as, electronics packages, Microwave packages,C Packages,laser Sub-mounts,etc.
