Beryllium sheet metal.

Beryllium is used industrially in three forms. One of the highest strength copper based alloys available on the market today is beryllium copper also known as spring copper or beryllium bronze. Beryllium copper featuring beryllium copper alloys in a variety of forms. Beryllium was discovered by louis nicolas vauquelin in 1797 and first isolated by friedrich wöhler and antoine bussy in 1828.

The commercial grades of beryllium copper contain 0 4 to 2 0 percent beryllium. Browse our beryllium copper stock items in alloy 172 annealed quarter and half hard tempers from 0 003 to 0 060. Sr 200 which is a sheet beryllium metal manufactured by warm rolling billets of vacuum hot pressed block. Class 3 castings are recommended for welder components that carry current and are under heavy load including heavy duty offset electrode holders.

Full hard and mill hardened tempers are stocked on a limited basis. Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close packed hexagonal crystal structure. It is a soft metal that is both strong and brittle its low density and high thermal conductivity make it useful for aerospace and military applications. 4 beryllium copper beryllium copper alloys.

C17510 beryllium cda uns c 17510 c17510 beryllium copper is specifically recommended for projection welding dies flash and butt welding dies current carrying shafts and bushings. The modulus of elasticity of beryllium is approximately 50 greater than that of steel. Beryllium oxide called beryllia is known for its high heat capacity and is an important component of certain sensitive electronic equipment. The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel.

It is often selected by designers seeking high performance heat sinks and structural supports in military electronic and avionics systems and is well suited for satellite structures as a hot formed material. In its elemental form beryllium has a gray metallic appearance. 20c 10c 70c 165c 275c and more beryllium copper also known as beryllium bronze or spring copper is a copper alloy with 0 5 3 beryllium and sometimes other elements. As a pure metal as beryllium oxide and most commonly as an alloy with copper aluminum magnesium or nickel.

Commonly stocked beryllium copper mead metals carries alloy 172 beryllium copper in annealed quarter hard and half hard tempers from 0 003 to 0 060. It is also frequently used in x ray equipment and particle physics. Iarc lists beryllium as a known human carcinogen group 1 and notes that the work environment of workers involved in refining machining and producing beryllium metal was associated with an increased risk of lung cancer the greater excess was in workers hired before 1950 when exposures to beryllium in the work place.
