Tungsten Wire Application - Duplicator
Tungsten Wire Application - Duplicator
Tungsten wire application is used as electrode wire in duplicator. Gold-plated tungsten wire means tungsten wire is coated with a layer of gold, this section is a special tungsten tungsten wire, gold-plated mainly in order to prevent corrosion. Gold plated tungsten wire has more beautiful surface than black tungsten wire and cleaned tungsten wire. In addition, gold plated tungsten wire corrosion resistance is much higher than ordinary tungsten wire. It has a high temperature, corrosion resistance, high melting point, low thermal expansion coefficient and excellent performance. In addition to use in a duplicator, gold-plated tungsten wire can also be used as an ideal anti-corrosion electron emitting material in meteorology and other scientific research.
