However, the advantages of using beryllium copper in hazardous environments outweigh these disadvantages.

The original RVs had been metallic, some actually made of beryllium copper, which had been fairly sturdy.

It was beryllium, copper, and nickel, sort of rough for it had not been polished.

Most flute keys have needle springs, made of phosphor bronze, stainless steel, beryllium copper, or a gold alloy.

It is a bar of metal, usually steel but sometimes other metals like beryllium copper, bent into a triangle shape.

In solid form and as finished parts, beryllium copper presents no known health hazard.

Unlike most other materials, an instrument composed of beryllium copper will maintain a consistent tone and timbre for as long as the material resonates.

For a time, beryllium copper was used in the manufacture of golf clubs, with emphasis on wedges and putters.

Tempered beryllium copper is Alloy 25 (C17200 & C17300) which has been age hardened and cold drawn.

Tempered wire is most useful where the properties of beryllium copper are desired, but age hardening of finished parts is not practical.
