PDF Beryllium and Beryllium Compounds

Elemental beryllium (mol wt 9.01218, CASRN 7440-41-7) is a hard, grayish metal. It is also known as beryllium metal, beryllium-9, beryllium metallic, glucinium, or glucinum. It is one of the lightest of all metals and has one of the highest melting points of the lightest metals. Beryllium occurs naturally as a chemical component of certain kinds of

Copper Beryllium Alloys - Beryllium Copper Distributors

Copper Beryllium Alloys combine high strength with good electrical and thermal conductivities. The high strength of copper beryllium alloys is accomplished by either age hardening or precipitation hardening. Valued for their non-magnetic and non-sparking qualities, Copper Beryllium Alloys are available as high-strength and high conductivity alloys.

Beryllium - Properties, History, and Applications

Jan 15, · In order to produce high-purity beryllium metal, the hydroxide form is dissolved in ammonium bifluoride and heated to above 1652°F (900°C), creating a molten beryllium fluoride. After being cast into molds, the beryllium fluoride is mixed with molten magnesium in crucibles and heated. This allows pure beryllium to separate from the slag (waste material).
