Beryllium is found in about 30 mineral species, including bertrandite, beryl, chrysoberyl, and phenacite, according to the Los Alamos National Laboratory. Beryl and bertrandite are the most important commercial sources of the element and its compounds. Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Beryllium copper is also used in windshield frame, brake discs, support beams, and other structural components of the space shuttle.
