Introduction to the characteristics of high-purity tungsten electrodes
High-purity tungsten electrodes have good thermal stability.
Because the melting point of tungsten is as high as 3410℃, high-purity tungsten electrodes can maintain stable performance in high-temperature environments and are not easy to ablate and melt. This makes high-purity tungsten electrodes have excellent durability and reliability under high-temperature conditions.
High-purity tungsten electrodes have excellent electrical conductivity.
Tungsten has good electrical conductivity. In electronic devices, high-purity tungsten electrodes can provide better current transmission effects, reduce current loss, and improve the working efficiency of electronic devices.
High-purity tungsten electrodes also have excellent corrosion resistance.
Tungsten has high chemical stability, which allows high-purity tungsten electrodes to be used in harsh working environments, are not easily corroded and damaged, and increase the service life of the electrode.
