Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity. Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites. Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.
