Answer
Beryllium Copper (typically Alloy 25) is selected for applications requiring non-magnetic properties and high electrical conductivity. It is frequently used in medical imaging (MRI) equipment and sensitive electronic sensors where ferrous materials would interfere with signals. CuBe can be heat-treated to reach tensile strengths comparable to alloy steels (up to $190$ ksi). Ezenkívül kiváló korrózióállóságot biztosít a tengervízben, és „szikramentes”, így alkalmas a bányászat és a robbanóanyag-ipar veszélyes környezeteire.
