Pure copper has a K value of 397 W m − 1 K − 1 (see Table ), and an IACS electrical conductivity of 102%. When copper is alloyed with 2% beryllium and heat treated, very fine precipitates of a strong copperberyllium compound form. In this condition, the tensile strength is increased from 300 MN m − 2 (fully workhardened pure copper ...
