99.95% Mo1 Straightened Molybdenum Wire Straight Moly Wires Diameter 0.5mm to 3.0mm
Molybdenum 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, intermediate molybdenum layers.

Straight Moly Wire Application:
The molybdenum wire is principally used in the high-temperature field of molybdenum furnace and radio tube outlets, also in thinning the molybdenum filament, and the molybdenum rod in heating materials for high-temperature furnace, and side-bracket/bracket/outlets wire for heating materials.
1) For making grid wire, hooks and mandrel wires of filaments
2) For hi-temperature resistant supports and hooks, leads and luminescent materials
3) Production of heaters for hi-temperature furnaces
Advantages of Molybdenum Wires:
1. Molybdenum wires high pricision,line diameter tolerance control at less than 0 to 0.002mm
2. The ratio of breaking wire low,processing rate is high,good performance and good price.
3. Can finish the stable long time continuous processing.
