Black tungsten wire is a filament made of pure or doped tungsten, usually showing a black surface. It has the characteristics of high melting point, high strength, and high hardness, so it is widely used in high-temperature furnaces, electronic equipment, aerospace and other fields.
The manufacturing process of black tungsten wire usually includes material selection, smelting, ingot casting, extrusion, drawing and other processes. During the manufacturing process, it is necessary to control the corresponding parameters, such as temperature, pressure, die hole diameter, etc., to ensure that the produced black tungsten wire has the required diameter and surface quality.
The application fields of black tungsten wire are very wide. In the field of electronic equipment, black tungsten filaments are used to make filaments and heating elements in light bulbs, electron tubes, transistors and other products. In addition, black tungsten wire is also used to manufacture heating elements for high-temperature furnaces and aerospace engine parts. In the field of high-speed cutting, black tungsten wire is used to manufacture superhard cutting tools and molds.
In short, black tungsten wire is a very important metal material with wide application value and development prospects. Its manufacturing requires multiple processes and technical requirements, and each process requires strict quality control and technical requirements. Only in this way can high-quality and high-stability black tungsten wire be manufactured to meet the needs of different fields.
