About Beryllium (Be) Foil/Sheet
Beryllium has been paid more and more attention as a new material. Beryllium is an indispensable precious material in atomic energy, rocket, missile, aviation, aerospace, and metallurgical industry.
Among all the metals, beryllium has the strongest ability to transmit X-rays, and thus is known as metallic glass. Therefore, beryllium is an irreplaceable material for making small windows of X-ray tubes.
Beryllium Foil/Sheet is produced by vacuum hot pressing and rolling. The products are mainly used in X-ray tubes, detectors, and windows of low-energy photon sources.
Typical Applications:
The Beryllium Foil/Sheet produced by vacuum hot pressing and rolling process has excellent permeability to X-rays, so the beryllium sheet can be used as a window material for X-ray tubes, detectors and low-energy photon sources.
NC Elements is a professional supplier of Beryllium metal, in the forms of foils, sheets, and discs. We can also provide the X-Ray window assemblies on request. Please contact us for more details.
