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.


Chemical Composition of RWMA Class 4 Beryllium Copper Alloys:

Be 1.80-2.00%
Co+Ni 0.20% Min.
Co+Ni+Fe 0.60% Max.
Others 0.50% Max.
Cu Balance
Note Cu+Be+Co+Ni+Fe:99.50% Min

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.
