Beryllium copper does not possess radioactivity. It is a material formed by alloying copper with beryllium and other metal elements, and is mainly used in high-end manufacturing fields.

Beryllium copper is a high-performance alloy made mainly of copper and containing an appropriate amount of beryllium and other alloying elements (such as nickel, cobalt, etc.). This alloy, due to its excellent mechanical properties, good electrical and thermal conductivity, and corrosion resistance, has been widely applied in various fields such as electronics, aerospace, and mechanical manufacturing.
Radioactivity mainly stems from the instability of atomic nuclei, causing atoms to spontaneously emit rays (such as alpha rays, beta rays, etc.). However, the copper, beryllium, and other metal elements in beryllium copper are all stable elements, and their atomic nucleus structures are relatively stable, making them less prone to radioactive decay. Therefore, from the perspective of radioactive sources, beryllium copper does not possess radioactivity.
