Description of Beryllium Round Foil

Beryllium is the lightest rare metal with the smallest atomic coefficient and has a certain penetration effect on X-rays; it is the most commonly used window material for X-ray analysis and detection equipment.

Beryllium Round Foil is made of high-purity beryllium material. Beryllium Round Foil has the advantages of high purity, high radiation transmittance, good vacuum sealing, wear resistance, corrosion resistance, and long service life. It can seal the light tube and keep X-rays. The vacuum inside the tube and its role in filtering low-performance X-rays.

Beryllium Round Foil is suitable for use in high-resolution medical radiography, disease analysis equipment, homeland security imaging equipment, or high-frequency speakers.

Features of Beryllium Round Foil

• Very low density (1.85 g/cm³), specific stiffness is very high

• Low atomic number and high gamma-ray or X-ray transmissivity

• Conductivity is high thermally, and expansion is low, while outstanding stability is thermally

• Non-ferromagnetic, high-temperature (>400°C under vacuum)

• Surfaces are mirror quality, and ultra thin and rollable.

Applications of Beryllium Round Foil

• Ultra-thin windows for synchrotron radiation and X-ray tubes
• End windows for neutron scattering devices
• Lightweight reflector substrates for space satellites
• Semiconductor EUV lithography mask carriers
• High-energy physics beam tube windows
