Tungsten copper WCu materials are used for arcing contacts in SF 6 circuit breakers for high and medium voltage appli ions. At the heart of the switching chamber, WCu arcing contacts are exposed to extreme mechanical and thermal stresses. During arcing, the

Silver Tungsten Carbide Contacts for Circuit Breaker ...

Silver Tungsten Carbide Contacts for Circuit Breaker Appli ions. Timo M 252tzel, Bernd Kempf. Umicore AG and Co. KG Business Unit Technical Materials 63457 HanauWolfgang, Germany timo.muetzel eu.umicore.com. AbstractSilver tungsten carbide AgWC contacts are often applied to circuit breaker appli ions due to their good arcing erosion properties.

Copper Tungsten Products EBiz Center of CTIA Tungsten ...

Copper tungsten may be used as an electrical contact material. In the most severe appli ions associated with power generation and transmission the switch may be totally immersed in oil. In these cases there is no advantage in using the tarnish resistant silverbased materials, as oxidation is prevented by the exclusion of air.

Coppertungsten Wikipedia

When the contact is very fine grained VFG , the electrical conductivity is much higher than a normal piece of copper tungsten. Copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding. CuW is usually a contact for vacuum, oil, and gas systems. It is not a good contact for air since the

Electrical Contacts are made from a Variety of Materials

Silver Tungsten Carbide AgWC : Silver tungsten carbide has proven to be an excellent material because of its ability to resist contact sticking or welding and also because of its resistance to oxidation. Because it is a harder material than silver tungsten, AgWC is more resistant to arc erosion and contact

Tungsten and Molybdenumsilvertungsten Siwodur Materialssilvertungsten Carbide Siwodur C MaterialsSilverMolybdenum Silmodur MaterialsCopperTungsten Cuwodur MaterialsTungsten is characterized by its advantageous properties of high melting and boiling points, sufficient electrical and thermal conductivity and high hardness and density Table 1. It is mainly used in the form of brazed contact tips for switching duties that require a rapid switching sequence such as horn contacts for cars and trucks. Molybdenum has a much lesser importance as a contact material since it is less resistant against oxidation than tungsten.Both metals are however used in large amounts as compone

Copper Wettability On Tungsten Carbide Surfaces Request PDF

The wetting behavior of copper on tungsten carbide surfaces was investigated through the sessile drop method, at 1080 176C, in vacuum atmosphere. Tests were performed on three different types of ...
