[Know Tungsten] What is a Barium Tungsten Electrode? 46

Barium tungsten electrode is a high-performance cathode material with tungsten as the matrix and barium added. It is usually prepared by impregnation, where the active barium compound is impregnated into a porous tungsten matrix. Barium tungsten electrode combines the high temperature stability of tungsten with the efficient electron emission ability of barium. It performs well in strong electric fields and high frequency environments and is widely used in lighting, electric vacuum devices, lasers and plasma equipment, such as high-intensity gas…

[Know Tungsten] What is Cut-Resistant Tungsten Wire? 43

Cut-resistant tungsten wire is a high-performance metal wire with tungsten as the main component. It has the high hardness, high strength and high temperature resistance of tungsten. It is strengthened by adding rare earth elements such as rhenium or carbides, which significantly improves its wear resistance and mechanical cutting resistance. Cut-resistant tungsten wire is not easy to break during repeated cutting or friction. It is widely used in EDM electrode wire, anti-cutting gloves, photovoltaic silicon wafer cutting and other scenarios,…
