Beryllium. Beryllium, Be, atomic number 4. Melting point 1560K. A whitegrey alkaline earth metal. Widely used in the spacecraft industry right from its early preinterstellar history because of its high thermal stability and low density. It is also a very useful component of many alloys, both industrially and for specialist high tech components.
Beryllium. Beryllium fluoride is another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Beryllium is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spotwelding electrodes and nonsparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
Brush Performance Alloys produces two classes of copper beryllium alloys: high strength and high conductivity. The high strength copper beryllium alloys, which have good electrical and thermal conductivity, are used in applications such as springs, electronic connectors, bearings, molds and corrosion resistant hardware.

Chronic beryllium disease (CBD) means a chronic lung disease associated with airborne exposure to beryllium. Confirmed positive means the person tested has beryllium sensitization, as indicated by two abnormal BeLPT test results, an abnormal and a borderline test result, or three borderline test results. It also means the result of a
Beryllium is used in fire safety and detection equipment – keeping it in a constant state of readiness in case of emergency. Beryllium used in automobile and airplane braking systems ensures that you can stop on time every time. Discuss alloys – and why you might want to .
Common Name: BERYLLIUM CAS Number: DOT Number: UN 1567 (Powder) DOT Hazard Class: 6 (Poison) HAZARD SUMMARY * Beryllium can affect you when breathed in. * Beryllium is a CARCINOGENHANDLE WITH EXTREME CAUTION. * Breathing Beryllium can irritate the nose, throat and lungs. Bronchitis and/or pneumonia may occur 12 days after high exposure.
Engineering control of process equipment (eg, enclosure and local exhaust ventilation) should be used to prevent inhalation and skin contact with beryllium nitrate. In activities where overexposure is possible, wear a selfcontained breathing apparatus, goggles, gloves, and protective clothing.
Performance Alloys produces two classes of copper beryllium alloys: high strength and high conductivity. The high strength copper beryllium alloys, which have good electrical and thermal conductivity, are used in applications such as springs, electronic connectors, bear ings, molds and corrosion resistant hardware.
