Beryllium is an alkaline earth metal. It has low density and is silver-white in colour. It is found in multiple minerals, including beryl which has precious forms as emerald and aquamarine.
Beryllium is usually alloyed with copper or nickel to increase their thermal and electrical conductivity. These alloys are used to make items like gyroscopes, springs, electrical contacts, spot-welding electrodes, and non-sparking tools. Other alloys are used for aircraft, spacecraft, and satellites. Beryllium alloys tend to be stiff, lightweight, and stable over a wide range of temperatures (due to its high melting point), making them ideal for aerial equipment.
Beryllium's high melting point makes it useful in nuclear reactors and other nuclear work. Beryllium can reflect neutrons (neutron reflector), which lets nuclear reactors have a more even distribution of neutrons.
