Beryllide

Beryllide is an intermetallic compound of beryllium with other metals, eg. zirconium, tantalum, titanium, nickel, or cobalt.

Beryllides of cobalt and nickel have metallurgical importance as the precipitated phase in beryllium copper alloys.

In nuclear technology, beryllides are investigated as neutron multipliers.

Iron beryllide (FeBe5) fibers in iron aluminide matrix are investigated as a composite material.
