Laminated Sheets - Copper/Moly/Copper Click here for pdf data sheet (104k)
Cu/MoCu sheets have very high in plane conductivity provide by layers of copper and low thermal expansion provided by the inner layer of molybdenum. These laminated sheets have the ability to spread the heat from a concentrated heat source and then dissipate the heat through the layers. They Also:
Offer an economical solution to many applications
Will not delaminate and can resist repeated 850° C cycles
Available in several standard ratios and many thicknesses for tailored TE machining
WCu composites are made by infiltrating, under vacuum, uniform controlled porous blocks of tungsten with molten copper. This results in a material with an interconnected copper matrix that has high thermal conductivity in all axis, low thermal expansion, and good electrical conductivity, Copper content can range between 10% and 25%.
