Selection of Tungsten Wire in Glass Heating System 28

Tungsten wire has an extremely high melting point (about 3422℃) and is an ideal high temperature resistant material in glass heating system. Its resistivity is moderate, it can heat up quickly when heated, and it has good thermal stability and is not easy to deform or melt. Tungsten wire also has a low thermal expansion coefficient and can maintain structural stability at high temperatures. In addition, the chemical inertness of tungsten makes it difficult to react with glass or surrounding…
