Bright Molybdenum Copper Alloy Rod MoCu25 Diameter 25mm MoCu Alloy Rod Heat Sink Material
Molybdenum Copper Alloy Rod MoCu25 Diameter 25mm
1.Product Description of Molybdenum Copper Alloy Rod:
The excellent thermal conductivity of molybdenum-copper alloy makes it a suitable material for use as a heat sink. While the two alloys' characteristics are comparable, molybdenum-copper alloy has a lower density than tungsten-copper alloy. The preparation of molybdenum-copper alloy is mainly by dipping method, using high-quality molybdenum powder and oxygen-free copper powder, and applying isostatic pressing (high temperature sintering-copper infiltration), with fine structure, good arc breaking performance, good electrical conductivity and thermal conductivity. Well, there is little thermal expansion.
