BE0940 Beryllium (Be) Foil

Description of Beryllium Foil

Beryllium (Be) is a brittle, steel-gray alkaline earth metal. It is strong, lightweight, and has a modulus of elasticity 50% greater than steel. It is non-magnetic properties and has higher specific heat than any metal. Beryllium retains excellent properties at elevated and cryogenic temperatures, making this fascinating metal an ideal thermal conductor. 

Because of its low density and high thermal conductivity, beryllium has many applications in aerospace and military industries. Beryllium is also transparent to X-rays and other forms of ionizing radiation, making it a great material for X-ray windows. It is frequently used as a material in acoustic applications for its damping properties and high stiffness-to-weight ratio. 

Beryllium is relatively transparent to X-rays and other forms of ionizing radiation. Therefore, it is the most common window material for X-ray equipment and components of particle physics experiments.
The Beryllium foil could be as thin as 0.0008 inches and 100% tested for vacuum tight. The foils are supplied cut to shapes such as discs, rectangles, and other custom shapes.
