Tungsten copper back-cast

[W-core + Cu back-cast | TE-/TN-series]

In tungsten-copper back-casting, a tungsten core is back-cast with liquid copper to create a seamless, 100% bond. The compound thus combines the high hardness, wear and burn resistance of tungsten with the excellent electrical and thermal conductivity of copper. The result: durable, reliable components for applications with high temperature and current loads – e.g. electrodes and nozzles for plasma spraying, electrodes for resistance welding and components in X-ray technology. Below you will find our current product series (TE/TN series) with core materials (including W, WLa, WTh, WRe) and delivery forms.
