Tungsten Foil (Light Tight)
Tungsten foil (light tight) is used in engineering and research applications that require high radiation shielding and precise control of light exposure. Its high density and ability to absorb X-rays and gamma rays make it suitable for radiation protection in medical imaging and particle detectors. The material's low thermal expansion and stability under extreme temperatures make it ideal for use in laboratory vacuum chambers and electron microscopes, where maintaining controlled environments is essential. Tungsten foil's corrosion resistance also makes it valuable in aerospace components, such as rocket nozzle throats and re-entry vehicle ballast, where high thermal stability is critical. Additionally, it is used in high-performance industrial tools, including Electrical Discharge Machining (EDM) electrodes and hot-forming dies, where wear resistance and durability are crucial.
