Tungsten/Copper Alloy Foil (W80/Cu20)

Tungsten Copper Alloy Foil (W80/Cu20) features a high tungsten fraction that ensures superior strength, wear resistance, and arc erosion protection, combined with copper’s effective conductivity and heat dissipation. With 80% tungsten, this foil offers enhanced structural stability and reliability in harsh environments, while the 20% copper phase ensures conduction efficiency. Industries including aerospace, power electronics, and defense employ W80/Cu20 foils in rocket propulsion systems, power switching devices, and high-current contacts. Specific uses include EDM electrodes, conductive barriers in aerospace sensors, and erosion-resistant foils in pulsed-power systems. Research employs W80/Cu20 foils to study tungsten-copper phase integration, conductivity under thermal stress, and durability in repetitive electrical cycling. Its combination of toughness, arc resistance, and conduction ensures essential utility in aerospace, defense, and energy-intensive electronic applications.
