Application of tungsten copper electrode in the field of electric discharge machining
Electrical discharge machining (EDM), also known as electric discharge machining (EDM), continuously generates pulsed discharge sparks between the tool and the workpiece during the machining process. Its advantage is that it can process difficult-to-cut materials, very hard materials such as cemented carbide, and various High speed steel and even diamond and cubic boron nitride. Tungsten copper electrodes are widely used in the field of EDM due to their good physical and chemical properties. Tungsten copper electrode is an alloy material with tungsten and copper as its main components. It has the characteristics of high strength, fast heat dissipation, good electrical conductivity, excellent thermal conductivity, excellent high temperature resistance and arc ablation resistance, and is widely used. In fields such as electric discharge machining, resistance welding, and electrochemical machining. In EDM, tungsten copper electrodes can effectively improve processing efficiency, reduce electrode loss, improve the accuracy of molds and components, and can complete rough machining and finishing of products in one go. In addition, because the tungsten copper material has high strength and density, it can withstand greater mechanical pressure and heat, thus avoiding errors caused by electrode deformation. In order to ensure the stability during EDM and improve the utilization of...

The use of tungsten in electrochromic glass
The thin film coating will change the color of the film due to the absorption of external energy. This material is called an electrochromic material. The electrochromic effect of the tungsten trioxide film is closely related to its microstructure. Yellow tungsten oxide, tungsten trioxide, is a typical representative of inorganic electrochromic materials. The principle is to adjust the light transmittance by changing the size of the current to achieve dimming from transparent to opaque. Regarding the electrochromic mechanism of WO3 films, the current intervalence transition theory proposed by Faughnan is that due to the effect of an external electric field, electrons and cation minerals are simultaneously injected into WO3 from both sides of the film, and the electrons are captured by W atoms to form a localized state. The ion M+ resides in this area to form a dark blue tungsten bronze compound Mx WO3. There are W ions of different valence states in Mx WO3. The transition of electrons between adjacent W atoms of different valence states causes the color of the WO3 film to change. The yellow tungsten oxide electrochromic film utilizes the electrochromic properties of tungsten trioxide and is prepared by physical vapor deposition, chemical vapor deposition,...

Application and market research of tungsten and molybdenum rare earths in the field of new energy batteries
Metal tungsten is a transition metal and belongs to the Group 6 elements of the 6th cycle. Because the radius of tungsten ions is small, the electricity price is high, and the polarization ability is strong, it is easy to form complex anions. Therefore, tungsten is mainly in the form of complex anions (WO4)2-, which combines with cations such as Fe2+, Mn2+, and Ca2+ in the solution to form wolframite or Precipitation of scheelite. Metal tungsten is a silver-white metal with a hard and high density. Its density is 19.35 g/cubic centimeter, which is similar to gold. Its melting point is 3422°C and its boiling point is 5927°C. Tungsten has a slow evaporation rate and stable chemical properties. It is mainly used to manufacture filaments, high-speed cutting alloy steel, superhard molds, optical instruments, chemical instruments, etc. In addition to the above uses, tungsten metal can also be used in the battery field. It is understood that nanometer yellow tungsten oxide, needle-shaped purple tungsten oxide, rod-shaped purple tungsten oxide, tungsten disulfide hollow spheres, tungsten disulfide nanosheets, tungsten diselenide nanosheets, nanotungstic acid, nanometer tungsten nitride, sodium tungstate , zinc tungstate and other tungsten compounds can be well used in sodium-ion batteries (sodium...

How to choose tungsten target
Tungsten target is a high-purity, high-temperature stable material that is widely used in electronics, communications, aerospace, automobiles and other fields. The following analyzes how to choose tungsten targets from the perspectives of product structure, product selection, product advantages, usage scenarios, etc.: Product structure: Tungsten target is mainly composed of target core, target sleeve, cooling system, etc. The target core is the main component of the target material, and its material is generally pure tungsten or tungsten alloy. The target cover is mainly to protect the target core and also reduce the impact of thermal radiation on the surrounding environment. The cooling system is to dissipate the heat generated by the target at high temperatures in a timely manner and maintain the stability of the target. How to choose products: When choosing tungsten targets, you need to consider the following aspects. The first is the purity of the target. High-purity tungsten targets have better physical and chemical properties and can better meet the requirements of various high-precision applications. Next is the density and lattice structure of the target. These factors will directly affect the mechanical and thermal properties of the target. Finally, the target production process and manufacturer need to be...
