Environmental protection of cut-resistant tungsten wire
Cutting-resistant tungsten wire is a high melting point, durable material, widely used in photovoltaic silicon wafer cutting, electric spark wire cutting (EDM), precision machining, nuclear shielding and other fields. Combining its material properties, production process and actual application analysis, its environmental protection is mainly reflected in the following aspects: 1. Reduce resource-consuming pollution As a substitute for traditional high-carbon steel wire, the life of tungsten wire can reach 10-20 times that of similar materials (such as the life of EDM cutting wire is extended to more than 40 times), significantly reducing the frequency of replacement of metal consumables. Taking the mechanical processing industry as an example, the amount of metal waste generated by tungsten wire under the same output is only 5%-8% of high-carbon steel, and its high cutting accuracy can reduce the loss of raw materials. 2. Avoid the risk of toxic substances Tungsten-based alloys can replace harmful materials in many fields: Ray shielding field: tungsten-nickel-copper alloy replaces lead-containing protective materials (such as medical CT equipment shielding layer), avoiding lead pollution and increasing shielding efficiency by 70%; Electronic industry: replace cadmium-containing electrode materials to avoid heavy metal electroplating pollution; Military industry: as an environmentally friendly substitute for depleted uranium...

The role of molybdenum weight in single crystal furnace
The mainstream manufacturing method for single crystal is the Czochralski method. A very important component in the single crystal furnace of the Czochralski method is the weight. The weight is used to connect the seed crystal and the tungsten wire rope. The quality of the weight will directly affect the pulled single crystal.During the Czochralski method of growing single crystal silicon, a weight is connected to the seed crystal through a tungsten wire rope. The weight of the weight keeps the seed crystal in place and controls the growth rate of the crystal during the pulling process. The design and material selection of the weight need to consider its stability in a high temperature environment to ensure that the performance of the weight is not affected by temperature changes during the crystal growth process.The molybdenum content of the heavy hammer is not less than 99.95%, the physical density is above 9.9 g/cm3, and the high temperature resistance can reach above 1600°-1700°. The concentricity is the same as that of the molybdenum seed crystal chuck, the tolerance is within 0.02mm, the thread mouth is required to be smooth, without rotten teeth, and the product has a high finish. Function of the...

Molybdenum copper plate: multi-field application of high-performance alloy
Molybdenum copper plate is a plate made of molybdenum and copper through a specific process. It has shown broad application potential in many fields due to its unique physical and chemical properties. From the perspective of physical properties, first of all, molybdenum-copper alloy inherits the high melting point characteristics of molybdenum and can maintain stable performance in high temperature environments. This feature gives it a significant advantage in fields that need to withstand high temperature environments, such as aerospace and chemical equipment. At the same time, copper, as an excellent thermal conductive material, combined with molybdenum, makes molybdenum-copper alloy have excellent thermal conductivity. This feature is particularly important in fields such as electronic packaging, which can effectively improve the heat dissipation efficiency of equipment and ensure the stable operation of equipment. In addition to high melting point and good thermal conductivity, molybdenum-copper alloy also has good electrical conductivity. This feature makes it widely used in application scenarios that require electrical conductivity, such as electrodes and electric heating elements in the electronics industry. In addition, molybdenum-copper alloy also has high strength and hardness, and can withstand large loads and stresses, which provides strong support for its use in the manufacture of...

Application of high purity molybdenum sputtering target in liquid crystal flat panel displays
With the development of science and technology, molybdenum (Mo) has begun to emerge in many emerging fields, changing human life in all aspects. The most relevant to people’s lives is its application in the manufacture of flat-panel displays. Large-size high-purity molybdenum sputtering targets are the key core raw materials in the manufacture of liquid crystal flat-panel displays, and Mo is one of the preferred materials for sputtering targets for flat-panel displays. Such targets are needed for the screens of electronic products such as daily color TVs, smart phones, tablet computers, and some large household appliances, as well as the control display screens of some military communication equipment. How is the display of a flat-panel display achieved? Through two pieces of glass separated by vacuum, the glass on the back is used as the cathode. More than 500 million emitter tips are distributed on this piece of glass in the form of a field emitter array. The interval between the emitters is very small, much smaller than the pixels on the TV screen. The emitter tips can be controlled individually or in groups during display. It is made of Mo. This display using Mo has the advantages of wide viewing angle,...
