Tungsten/Copper Alloy Foil (W60/Cu40)

Tungsten Copper Alloy Foil (W60/Cu40) balances tungsten’s mechanical robustness with copper’s high conductivity, offering a material suitable for applications requiring strength, thermal control, and electrical transfer. With 60% tungsten, the foil provides strong wear resistance and arc erosion stability, while the 40% copper ensures effective conductivity and thermal management. Industries including aerospace, power electronics, and defense employ W60/Cu40 foils in high-current electrical contacts, thermal spreaders, and protective conductive barriers. Specific applications include EDM electrodes, welding electrodes, and heat-dissipating foils for aerospace sensors. In research, W60/Cu40 foils are studied for microstructural distribution of tungsten and copper phases, optimization of conductivity-strength balance, and stability under cyclic thermal and electrical loading. Their dual-function role in conduction and structural durability ensures continued value across aerospace, power, and defense applications.
