Tungstencopper WCu Plansee
circuit breakers. Tungsten copper WCu materials are used for arcing contacts in SF 6 circuit breakers for high and medium voltage applications. At the heart of the switching chamber, WCu arcing contacts are exposed to extreme mechanical and thermal stresses. During arcing, the temperature can reach levels 20,000 K, for instance.

The Tungsten content ranges from 50 to 70 by weight. This strong material has good mechanical properties and is highly resistant to arc erosion in contact welding. It is mainly used in oil devices to protect the contact from oxidation. CuWC50 and CuWC56 grades have excellent resistance to mechanical wear and are mainly used for electrical contacts. CuWC50, with higher copper content and electrical conductivity, is used in heavy duty contactors and transfer switches.
Tungsten Copper Contacts Suppliers matmetals
Product Description. Tungsten Copper Contacts Description: Owing to the good performance of electrical conductivity, tungsten copper contact can be used as electrical contact material, The high electrical and thermal conductivity of copper are combined with the arcresistant and nonwelding properties of tungsten or their carbides to form an extensive series of compositions.
TUNGSTEN COPPER DATASHEET High Performance Special Alloys
The hardness varies dependent on the Tungsten Copper mix but ranges from HB 115 to HB 260. Carbide tools are recommended for milling, turning and drilling. Machining and Finishing Coolant is optional and carbide inserts are recommended in most cases. Coolants should be nonalkaline and water soluble with high lubricity.
Electrical Contacts are made from a Variety of Materials
The CTI family of silver tungsten contact materials range from a low of 10 silver to a high of 90 silver. In addition to varying the composition, CTI engineers can modify the contact material by changing process parameters. This may include changing particle size, furnace temperatures, as well as the addition of additives.
Tungsten and Molybdenum Based Materials Electrical Contacts
Coppertungsten CUWODUR materials with typically 5085 wt tungsten are produced by the infiltration process with the tungsten particle size selected according to the end application Figs. 5 8 Table 5. To increase the wettability of the tungsten skeleton by copper a small amount of nickel lt 1 wt is added to the starting powder mix.
