Tungsten Copper Alloy Tube combines the strength and the erosion resistance of tungsten with the heat dissipation and the conductivity of copper to make a tube for high-performance systems. This tube uses tungsten to guarantee wear resistance and arc stability, while copper adds to the excellent thermal management and electrical pathways. WCu tubes are used in thermal conduits and current-carrying components in the aerospace, nuclear systems, and power electronics industries, as well as in high-voltage systems. These tubes are used as EDM guide tubes, aerospace electronics cooling channels, and fusion energy devices' conductive pathways. In WCu tube research, phase compatibility, optimisation of conductivity, thermal and electrical cycling of structural reliability are the most common topics. Advanced aerospace and power systems technologies rely on the WCu tube for its exceptional combination of toughness, formability, and functional balance.
