Beryllium copper is a copper alloy containing 0.5 to 3% Beryllium. It can also contain some lead to improve machinability. Most used beryllium copper alloys are CuBe2 | C17200, CuBe2Pb | C17300 and CuBe1,7 | C17000. Thanks to its great compromise between conductivity, mechanical properties it has been widely used in rolled and wire formats.
