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.
Introduction of RWMA Class 4 Beryllium Copper Alloys:
C17200 Beryllium Copper is an excellent material for a number of
applications. C172 has excellent bearing properties with extremly
high compressive strengths. C17200 also has siginificant non
corrosive properties when exposed to harsh conditions. This alloy
also has great galling resisitance. C17200 has a relative magnetic
permability very close to 1.00, making it transparent to the effect
of magnetic fields. This alloy is non sparking.

Age Hardenable Tempers
This term means the material can be strengthened by simple heat
treatment after stamping or forming. The strength level will be
roughly doubled by optimum heat treatment.
