Tungsten/Copper Alloy Tube (W60/Cu40)

Tungsten Copper Alloy Tube (W60/Cu40) delivers a balance of tungsten’s high strength and erosion resistance with copper’s conductivity and heat dissipation in a tubular geometry suited for high-performance systems. With 60% tungsten, the tube ensures arc stability and wear resistance, while 40% copper provides excellent thermal management and electrical pathways. Industries including aerospace, nuclear systems, and power electronics employ W60/Cu40 tubes in thermal conduits, current-carrying components, and high-voltage systems. Specific applications include EDM guide tubes, cooling channels for aerospace electronics, and conductive pathways in fusion energy devices. In research, W60/Cu40 tubes are studied for phase compatibility, conductivity optimization, and structural reliability under thermal and electrical cycling. Their combination of formability, toughness, and functional balance ensures essential use in advanced aerospace and power system technologies.
