Tungsten/Copper Infiltrated Composites , Molybdenum/Copper Composites
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%.
Molybdenum/Copper Composites
MoCu alloys are made by sintering molybdenum and copper together. This results in a heat sink of lower density, low CTE and excellent thermal conductivity. Other features include:
¡ñ Sheets can be stamped when moly is less than 70%
¡ñ Non magnetic
¡ñ Relatively low density
¡ñ Can be gold or nickel plated
