MarkeTech Mo70Cu Moly/Copper Heat Sink Material (discontinued **)
Categories:	Metal; Metal Matrix Composite; Nonferrous Metal; Molybdenum Alloy; Refractory Metal
Material Notes:	MoCu alloys are made by sintering molybdenum and copper together. This results in a heat sink of lower density than tungsten-based materials, low thermal expansion, and excellent thermal conductivity. Other features include Sheets can be stamped when moly is less than 70% Non magnetic Can be gold or nickel plated Data provided by MarkeTech International. MarkeTech International is no longer in business.
