Molybdenum Wire Survey:
Molybdenum (Molybdenum) is a chemical element, its chemical symbol is Mo, and its atomic number is 42. is a VIB group metal.
Molybdenum Wire Characters:
Molybdenum is a gray transition metal. The pure metal of molybdenum is silver-white and very hard. Adding a small amount of molybdenum to steel can harden the steel.

The application of molybdenum wire electric melting heating technology in soda lime glass, boron glass and other systems has been widely reported. But in the production of other melts such as cast stone and liquid coal slag, the electric melting heating process is used. In this aspect, we have done some useful exploration work.
Strength of edm molybdenum wire: high tensile strength, good wear resistance and long service life.
Cold-drawn edm molybdenum wire: The cold-drawn production technology is adopted, with high strength and good surface quality.
EDM Molybdenum wire with fixed length: In addition to the characteristics of high-strength molybdenum wire, it also has the advantages of fixed length, convenient use and high utilization rate.
The molybdenum wire is then made into molybdenum stranded wire by mechanical or manual methods according to the requirements of the commodity. There are different specifications such as large stranded wire, small stranded wire and long stranded wire. When twisting the wire, put the wire sheet on the twisting hook, wrap it tightly, flatten it, and straighten it, and then use the mechanical power to make the twisting hook rotate a certain number of times. After removal, it becomes a skein with twisted twist.
If the molybdenum wire is installed too loosely, the molybdenum wire will vibrate greatly, which will not only cause wire breakage, but also directly affect the surface roughness of the workpiece due to the vibration of the molybdenum wire. However, the molybdenum wire should not be installed too tightly. If it is too tight, the internal stress will increase, which will also cause the wire to break. Therefore, the molybdenum wire should be properly tightened during the cutting process. The newly installed molybdenum wire should be tightened first and then processed. Do not use too much force when tightening the wire. Molybdenum wire becomes loose due to its own stretching after processing for a period of time. When the elongation is large, the vibration of the molybdenum wire will be aggravated or the molybdenum wire will overlap on the wire storage drum. Make the wire run unstable and cause wire breakage. The tightness of the molybdenum wire should be checked frequently, and if there is slack, it should be tightened in time.
