Tungsten/Copper Alloy Bar (W72/Cu28)

Tungsten Copper Alloy Bar (W72/Cu28) combines tungsten’s high melting point and mechanical strength with copper’s excellent electrical and thermal conductivity. The 72% tungsten phase ensures outstanding wear resistance and structural integrity, while copper provides efficient heat dissipation and electrical performance. Industries including electronics, aerospace, and defense employ W72/Cu28 bars for electrical contacts, heat sinks, and rocket nozzle components. Specific applications include electrical discharge machining (EDM) electrodes, spot-welding electrodes, and thermal management systems for high-power electronics. In research, W72/Cu28 alloy bars are studied for arc-erosion behavior, thermal conductivity optimization, and reliability in pulsed-power systems. Their ability to withstand extreme heat, stress, and electrical cycling ensures continuing relevance in aerospace propulsion, power electronics, and precision manufacturing technologies.
