2018/12/07 0183 32Tungsten 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 temperature can reach levels 20,000 K, for instance.
TUNGSTEN COPPER and SILVER TUNGSTEN ELECTRICAL ...
Tungsten Copper is used for ECM electrodes because it conducts high current and resists deformation and abrasion from the high velocity movement of the electrolyte. RESISTANCE WELDING High hardness and high strength at elevated temperatures and good electrical and thermal conductivities make these materials particularly suited for resistance welding

2 /Tungsten copper alloy is used to make engines and electrical devices. The alloy is also made into sheet metal, tubing and plate metal. This allows the CuW electrodes to have a longer service life than the graphite electrodes.

Copper contacts have the advantage that their relatively modest price permits them to be larger, so that higher contact forces can be used and larger wear can be tolerated. The aspot temperature will also be lower, because the good thermal conductivity will dissipate the local heat to the

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

2016/06/23 0183 32So, in the future, some are proposing to replace tungsten with cobalt for the contacts in the MOL. While silicide contact resistance has already emerged as a performancelimiter, by the 10nm nodes, the Wbased MOL resistances in smaller contact structures also becomes significant, said Vimal Kamineni, member of the technical staff at GlobalFoundries , in a recent presentation.
Coppertungsten tungstencopper, CuW, or WCu is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy. The material ...
