0.18mm*2000m molybdenum wire for EDM cutting
0.18mm wire cut molybdenum wire is a fine metal wire made from high-purity molybdenum through multiple processes such as powder metallurgy, rotary forging, and cold drawing, specifically designed for wire cutting electrical discharge machining. This specification is the most widely used molybdenum wire model in wire cutting processing, mainly used for precision cutting of various conductive materials such as mold steel, hard alloys, and magnetic materials.

1. High strength and anti breakage: Made using cold drawing technology, the tensile strength far exceeds the national standard, which can effectively reduce wire breakage problems during cutting and improve processing stability.
2. Excellent discharge performance: High purity molybdenum material has strong resistance to electrical corrosion, low self loss, can ensure machining accuracy and extend service life.
3. Good processing stability: low elongation, easy to maintain constant tension, and can also maintain high efficiency in high current (such as 3.5A) processing.
4. Vacuum packaging: Regular products often use vacuum packaging to prevent oxidation and mold growth of molybdenum wire, making it easy to store for a long time.
1. Molybdenum Powder Production
( This step is crucial for obtaining high-purity molybdenum material.)
2. Pressing and Sintering
(This step helps to achieve the desired density and mechanical properties)
3. Wire Drawing
( This process involves multiple drawing steps to achieve the desired wire diameter)
4. Cleaning and Surface Treatment
(This is important for ensuring the wire’s performance during the EDM process)
5. Spooling
(The spooling process ensures that the wire is properly wound and can be easily fed into EDM machines)
Mold manufacturing: precision cavity and core processing of injection molds, stamping molds, die-casting molds, etc. (especially hard alloys, quenched steel).
Precision component manufacturing: high hardness complex parts in aerospace (turbine blades, nozzles), automotive (fuel injectors, synchronizing rings, piston rings), medical equipment (surgical instruments, implants).
Electronics and Semiconductors: Micro cutting of conductive materials such as lead frames, microstructure components, electrode molds, etc.
Energy equipment: difficult to process materials such as wind power gears, nuclear power components, and battery electrode molds.
Tools and measuring tools: contour machining of wire drawing dies, punches, fixtures, and precision cutting tools.
In terms of diameter, the diameter of wire cut molybdenum wire is usually 0.18mm, which is a common specification. In addition, there are other diameters available, such as 0.2mm, 0.25mm, etc. These molybdenum wires with different diameters are suitable for different wire cutting needs.
In terms of length, the length of molybdenum wire is usually 2000 meters or 2400 meters, and the specific length may vary depending on the brand and product. Some products offer fixed length options, such as 2000 meters fixed length, while others offer non fixed length options, allowing users to choose the appropriate length according to their own needs.
1. Usage frequency: The higher the usage frequency, the shorter the lifespan of wire cut molybdenum wire. Because molybdenum wire is prone to wear and stretching during use, resulting in damage. Therefore, the normal maintenance and scheduling of downtime for the machine are key to extending the lifespan of wire cutting molybdenum wire.
2. Material of wire cut molybdenum wire: The material of wire cut molybdenum wire also affects its lifespan. Common materials include hard alloys, high-speed steel, pure tungsten, etc. Different materials have different characteristics and lifetimes. Hard alloy molybdenum wire has high hardness and wear resistance, and can maintain the sharpness of the blade for a longer period of time during use. Its lifespan is generally around 120-150 hours; The service life of high-speed steel molybdenum wire is generally 80-120 hours; The service life of pure tungsten molybdenum wire is relatively short, usually around 50-80 hours.
3. Working environment: The environment in which the wire cutting machine operates during the processing can also affect the lifespan of the molybdenum wire. For example, when processing materials with higher hardness, the lifespan of wire cut molybdenum wire is shorter compared to processing materials with softer hardness. Therefore, it is necessary to pay attention to strategies and coordination during the processing of workpieces.
