Beryllium is a silver gray mettalic element that occurs naturally in about 30 minerals. It is lighter than Aluminum yet stiffer than steel. Beryllium gives Copper the strength of steel with the conductivity of a Copper Alloy.
Because of the excellent fatigue resistance, beryllium copper is widely used for springs, pressure responsive diaphragms, flexible bellows, connectors, contacts and relays, which are all subject to cyclic loading. The anti-galling, strength and good corrosion resistance led to the widespread use of beryllium copper for down hole drilling tools for the oil and gas industry.
