Tungsten Contacts
Tungsten Contacts Description:
Tungsten contacts are one of the most commonly used electrical contact materials in various electrical appliances. The higher the purity of tungsten, the better the performance.Tungsten contacts can be made of tungsten rods, tungsten sheets or tungsten discs by brazing and pressing,and have high melting point, slow evaporation rate, good electrical and thermal conductivity, high bending strength, good arc erosion resistance, on-off current Strong capacity, low current consumption, good wear resistance, longer cycle life and low price, and many other advantages.
Tungsten Contacts Application:
Tungsten contacts are widely used in industries such as industry, agriculture, electronics, technology and automotive. Tungsten contacts are often used in high voltage equipment, relays (EMR or electromechanical relays), AC contactors, various automatic switches, electric horns and magnetos, etc.In addition to producing tungsten contacts, our company also produces high-quality tungsten copper contacts, tungsten-molybdenum products and high-purity tungsten products (such as tungsten rods, tungsten tubes, tungsten boats and tungsten crucibles, etc.).
