Molybdenum Copper alloy is the composite material of Molybdenum and Copper. It has the similar performances as Tungsten Copper alloy. But its density is less than Tungsten Copper alloy’s, so it is more suitable for spaceflight and navigation industries.

J D Global Trading Company has been providing customers over the past years with the most advanced hermetic connector and packaging technologies available to provide a controllable expansion composite matrix, yielding superior material stability and uniform thermal expansion characteristics to provide the designer a practical solution to meet critical thermal parameters.

Advantages of Molybdenum Copper (MoCu):

Thermal expansion can be design; High thermal conductivity; Precision flatness capability; Bondable gold plating; Thickness from .004" to .500"; Zero corner radius; Integrated ribs; Precision complex geometry; Low thermal expansion; Good electrical conductivity; High wear resistance; More lighter than W-Cu.
