Description of High Purity Molybdenum Wire
Molybdenum is a silvery gray metal that has a very high melting point (at 4730 degrees Fahrenheit, 2000 degrees higher than steel), and about 80% of molybdenum is used to make many types of steel alloys, such as high-strength alloys and superalloys.
High Purity Molybdenum Wire is mainly made of molybdenum rods through channel rolling, rotary forging, rolling and stretching into filamentous products of various diameters. According to different surface treatments, it can be divided into black molybdenum wire, bright molybdenum wire and sprayed molybdenum wire. Among them, black molybdenum wire is mainly used to make heating parts, hooks, core wires, and other products of electronic vacuum devices. White molybdenum wire can be used in wire cutting machines and electronic vacuum components.
High Purity Molybdenum Wire has a series of advantages such as high tensile strength, small elongation, high temperature resistance, stable chemical properties, high cutting precision, long service life and low price and cost. It is very suitable for the high-temperature furnace industry, the lighting industry, EDM and electronic engineering and other fields. When purchasing Moly Wires, pay special attention to its flatness, straightness and surface finish.
Precision wire drawing process of High Purity Molybdenum Wire
The whole process of wire drawing
Blank preparation:
Sintered molybdenum rod (Φ8mm, density>99%), hot forging (1200℃) to Φ2mm, grain aspect ratio>10:1.
Multi-pass wire drawing:
Diamond die (aperture reduction rate 10-15%/pass), intermediate annealing (1000℃/H₂, after each pass).
Ultimate processing:
Electrolytic polishing (H₂SO₄:CH₃OH=1:3), diameter tolerance ±0.5μm (Φ0.1mm wire), surface Ra＜0.05μm.
Process challenges
Wire break prevention and control:
Online laser diameter gauge (accuracy ±0.1μm), real-time adjustment of tension, wire break rate <0.1 times/10,000 meters.
Size limit:
Ultra-fine molybdenum wire (Φ5μm) requires ultrasonic-assisted drawing, and the breaking strength is >3GPa (nanomechanical test).
Features of High Purity Molybdenum Wire
High strength and high rigidity: Even at a thin diameter, high-purity molybdenum wire still has good tensile strength, reducing the risk of wire breakage during processing.
Good electrical conductivity: It can effectively conduct pulse current to ensure stable discharge and high cutting efficiency.
Strong wear resistance: The surface hardness is high, making it not easy to wear during processing, and the service life is long.
High dimensional accuracy: The wire diameter consistency is good, and the roundness is excellent, which is conducive to precision cutting and high-quality surface formation.
Good stability: The wire performance can still be kept stable under long-term continuous work, and the processing quality is consistent.
Corrosion resistance: At room temperature, the chemical properties of molybdenum are relatively stable and can remain stable in air or water.
Low thermal expansion coefficient: The thermal expansion coefficient of molybdenum is low, only 4.9×10⁻⁶/K, which means that the size of the molybdenum material changes very little when the temperature changes.
Applications of High Purity Molybdenum Wire
High-precision mold processing, such as injection molds, semiconductor molds, and processing complex contours (such as micro-tooth shapes), with an accuracy of up to ±3μm.
Chip bonding wire: In the semiconductor industry, Φ1.0-6.0mm molybdenum wire is used for chip bonding wire.
Bulb parts: used to make brackets for filaments made of tungsten, leads for halogen bulbs, and electrodes for gas discharge lamps and tubes.
