S-200-F GRADE BERYLLIUM

S-200-F grade beryllium is a vacuum hot pressed grade of beryllium consisting of a minimum of 98.5% beryllium.

S-200-F is used as an optical substrate and support bench in:

  • Numerous astronomical telescopes
  • In fire control and FLIR systems
  • In spacecraft and weather satellites
  • in nuclear applications that do not require the higher purity of S-65.

S-200-F is commonly certified to the Materion specification S-200-F. It can also be certified to the industry specification AMS7906 prepared by SAE Aerospace.
