"Of all the metals, beryllium has one of the highest melting point. Its modulus of elasticity is approximately 1/3 greater than steel. It is nonmagnetic, resists attack by concentrated nitric acid, is an excellent thermal conductivity and it is highly permeable to X-rays. At a standard temperature and pressure it resists oxidation when exposed to air. "

As an alloying agent in the production of beryllium copper.

Sheets of beryllium foil are used with X-ray detection diagnostics.

For the reproduction of microscopic integrated circuits in the field of X-ray lithography.

As a neutron reflector and moderator in nuclear reactors.

In nuclear weapons to surround the plutonium sphere which reduces the mass of the sphere.

In neutron sources where it is mixed with an alpha emmiter like polonium 210, radium 226, or actinium 227.

In the making of gyroscopes, various computer equipment, watch springs and instruments that requires light-weight, rigidity and dimensional stability.

It is also required in those applications where an excellent head condutor, with high strength and hardness and with a very high melting point is needed. Even it should act as an electrical insulator.

Once used in fluorescent lighting tubes.

Answer 2

Perhaps its best-known use is in a beryllium-copper alloy, commonly called BeCu. There are many other more exotic uses. See the list of applications in:
