Re-Drawn Molybdenum Wire
Re-drawn molybdenum wirerefers to a medium- to coarse-diameter molybdenum wire produced by drawing sintered molybdenum rods or hot-rolled molybdenum materials through multiple steps of thermal treatment and wire drawing. This product is primarily used as an intermediate material for the production of fine molybdenum wire, such as filament wire, electrode wire, and precision electrical wire. It features excellent workability, uniform dimensions, and a stable internal structure.
Product Features
High Purity
Made from high-purity molybdenum (≥99.95%), ensuring excellent thermal stability and corrosion resistance in downstream applications.
Excellent Workability
The wire exhibits a suitable balance of strength and ductility, facilitating multiple drawing passes without issues such as wire breakage or cracking.
Uniform Size and Dense Structure
Process-controlled recrystallization and grain refinement ensure a uniform and compact microstructure, which is beneficial for precision wire drawing.
Defect-Free and Superior Drawability
Strict quality control eliminates internal defects such as inclusions, porosity, or microcracks, making it ideal for high-speed, precision wire-drawing equipment.

Main Applications
1.Re-drawn molybdenum wire is primarily used as a pre-drawing material for fine molybdenum wire and is widely employed in the following downstream applications:
2.Filament Wire: for incandescent lamps, halogen lamp supports, xenon lamps, etc.
Electrode Wire: for X-ray tubes, electron guns, ion sources, and other high-precision components.
3.Heating Elements: for high-temperature furnaces and crystal growth systems.
Spray Wire Precursor: for plasma and thermal spray processes.
Technical Advantages and Processing Control
1.Multi-stage vacuum annealing or hydrogen-protected annealing improves ductility and drawing consistency;
2.Precise grain size control prevents over-recrystallization that can cause brittleness or wire failure;
3.Customization available to match customer drawing dies, optimizing compatibility and drawing efficiency.
