Molybdenum Wire for EDM Machine
Molybdenum wire has outstanding electrical and heat-conducting capabilities and relatively high tensile strength. Thermal conductivity is approximately 50% higher than that of steel, iron or nickel alloys. It consequently finds wide usage as heat sinks. Its electrical conductivity is the highest of all refractory metals, about one third that of copper, but higher than nickel, platinum, or mercury. The coefficient of thermal expansion of molybdenum plots almost linearly with temperature over a wide range. This characteristic, in combination will raise heat-conducting capabilities, accounts for its use in bimetal thermocouples.
