Can Molybdenum Really Cut Through Steel Plates?

Molybdenum - Core Material for High-end Manufacturing and Energy Molybdenum is a gray metal and one of the core materials for energy and high-end manufacturing, making it a rare and strategic resource. Molybdenum, with the chemical symbol Mo and atomic factor 42, belongs to the sixth subgroup of the fifth cycle in the periodic table of the elements and is a refractory rare metal. Molybdenum is characterized by high melting point, high strength, high electrical conductivity, good thermal conductivity, corrosion resistance, etc. It has a wide range of applications in electrical, chemical and astronautical fields. In this paper, the geochemical parameters, history and future applications of the element molybdenum will be presented. Geochemical parameters of the element molybdenumDespite its superior physical properties, molybdenum is not found in large quantities on Earth, and can be used in small quantities.

Molybdenum's striking use in industrial cutting In industrial cutting, the element molybdenum appears in the form of a fine wire and plays an important role. This fine molybdenum wire is able to cut steel plates like a fish out of water, enabling precise cuts to be made, but one wonders why such a fine molybdenum wire is able to cut right through a solid steel plate. While the hardness properties of molybdenum wire are great, cutting steel plates seems like a bit of an exaggeration. In fact, industrial cutting of steel plates does not only rely on molybdenum wire, the principle of the cutting device also plays a key role. The principle of industrial cutting of steel plates is related to wire-cutting technology. Wire cutting technology, also known as EDM, was first discovered and developed by Mr. and Mrs. Lazarenko.
They used the high temperatures of an electric spark to melt metal and cut the process, which later evolved into wire cutting machines. A wire cutter uses a moving wire as an "electrode wire" to melt the material being cut by generating a pulsed electric spark. Therefore, when observing a wire cutter in action, we see sparks coming out. Molybdenum was chosen for wire cutting mainly because of its excellent corrosion resistance at high temperatures. The high temperatures generated during wire cutting can be withstood by elemental molybdenum, and the stability and form of molybdenum fulfill the requirements of wire cutting machines. Because of its physical properties, molybdenum has a very low coefficient of thermal expansion, which makes it perfect for acting as a "cutting wire", ensuring that the cut part is complete and within specification.
