About Beryllium

Beryllium is a softish metal of grey and silver color. It has quite a low density and quite a high melting point for the light metals of the Periodic Table. Beryllium is an alkaline metal which is toxic and resists to oxidation in normal temperatures. It is usually alloyed with such metals as nickel and copper to produce various types of wires, contacts, springs, etc., especially for producing aircrafts, communication devices, and many other things. This chemical element can be found in about 30 natural sources, including precious stones like aquamarine, emerald, and others, thus used in jewelry.
