Beryllium

Probably the most important use of beryllium is in radiation windows for X-ray tubes. Beryllium is ideal for this use as it has a very low absorption of X-rays.
Beryllium is used in the pipes of many high-energy particle physics collision experiments (such as the Large Hadron Collider). The stiffness of the metal allows a powerful vacuum to be created.
Beryllium is used as a lightweight component of military equipment and in the aerospace industry. It is used in high-speed aircraft, space vehicles and communication satellites.
It is one component of metal springs, non-sparking tools and electrical contacts.
Naval personnel use beryllium tools when working on or near naval mines.
Beryllium is used in the design of nuclear weapons. It is used as the outer layer of the pit in the primary stage. It is an excellent pusher for implosion and is very good at at reflecting neutrons.
The low weight and high rigidity of beryllium makes it perfect for use in high-frequency speaker drivers.
Beryllium oxide is an excellent heat conductor. Therefore, it is used as an insulator base plate in high-power transistors in RF transmitters for telecommunication purposes.
Beryllium mirrors can be used in telescopes.
