Description Of High Purity Beryllium Foil 99.9%
High Purity Beryllium Foil 99.9% is a thin, high-purity beryllium metal foil manufactured from pure beryllium with 99.9% purity. Beryllium is a lightweight, silver-grey metal with a density of 1.848 g/cm³, excellent X-ray transmissivity, and superior mechanical strength. These foils are widely used as X-ray windows in detectors, spectrometers, and medical imaging equipment.
Beryllium offers a unique combination of properties that make it ideal for X-ray window applications. With low density and low atomic number (Z=4), beryllium provides high transmissivity for low-energy X-rays, minimizing spectral contamination and improving detection sensitivity. The material also offers high strength even in thin gauges, excellent vacuum tightness, and good thermal stability.
High purity beryllium foils are available in ultra-thin gauges from 8μm, with surface finishes including as-rolled, vacuum-tight, and optically-dense. Custom sizes and shapes are available upon request. Typical applications include X-ray detectors (EDXRF, WDXRF, XRD), medical imaging systems, X-ray tubes, and analytical instruments.
