Tungsten/Rhenium Alloy Foil (Light Tight) (W90/Re10)

Tungsten Rhenium Alloy Foil Light Tight (W90/Re10) integrates tungsten’s density and heat resistance with rhenium’s ductility, engineered into a thin foil free of pinhole defects for optical and electronic precision. With 90% tungsten, the foil ensures structural integrity and thermal stability, while 10% rhenium increases flexibility, creep resistance, and weldability. Industries including aerospace, defense, and high-vacuum electronics utilize W90/Re10 foils in environments requiring both light-tight shielding and electrical performance. Specific uses include pinhole-free barriers in vacuum tube devices, conductive light-blocking foils for photonic detectors, and sealing layers in aerospace electronics. In research, W90/Re10 foils are studied for thermal shock resistance, defect prevention, and electronic emission properties. Their ability to combine optical sealing, electrical conductivity, and mechanical resilience in pinhole-free form ensures ongoing value in aerospace, defense optics, and advanced scientific instrumentation.
