Tungsten-copper WCu Plansee

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 temperature can …

Tungsten Carbide Powder Copper Contact Tips Powder ...

1. The component and quality of contact production made by Powder Metallurgy are more easy to control comparing with other manufacturing methods, because it can ensure uniformity of contact function. It is beneficial for ameliorating metallographic organization and improving function of contact materials by using advanced methods: chymic cladding, chemical sedimentation, pulverization, mechanization alloy.品牌: LONGSUN

Tungsten Carbide Copper Alloy AMERICAN ELEMENTS

The tungsten atom has a radius of 139 pm and a Van der Waals radius of 210 pm. Tungsten was discovered by Torbern Bergman in 1781 and first isolated by Juan Jos& 233; Elhuyar and Fausto Elhuyar in 1783. In its elemental form, tungsten has a grayish white, lustrous appearance.Compound Formula: WC/Cu

Tungsten Copper Electrode, Heat Sink W Cu Properties ...

Copper Tungsten Contact. Copper tungsten contact presents high closing and breaking performance in appli ions of high voltage circuit breakers, no matter what the interrupting medium is, e.g. an oil, vacuum, SF6 gas, or air environment. When the low melting point copper particles melt and evaporate from the tungsten skeleton, those particles absorb large amounts of heat generated by the electrical arc. Apart from the cooling effect of copper tungsten, the high melting point tungsten …

TUNGSTEN COPPER - DATASHEET - High Performance Special …

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 non-alkaline and water soluble with high lubricity. Due to the material characteristics, particularly the low thermal expansion, very close tolerances and fine finishes can be …预计阅读时间:5 分钟
