Ductile cast iron with different copper content was precipitation hardened. Cast iron with 0.48 % Cu content was ferritized. That operation was ended with rapid quenching, and then aged. Cast iron with 1.27 or 2.10 % Cu content was spheroid annealing. After rapid quenching cast iron was aged. Not alloy cast iron with small copper content (0.04 %) had a chemical composition similar to cast iron with 0.48 % Cu content. Such copper was for tests in order to obtain an answer for the question whether only copper is responsible for precipitate hardening effects. Metalographic microscope tests (LM, SEM) of mechanical properties (Rm, Rp, A5, Z, K and H) and x-ray diffraction tests were performed. It has been stated, that hardening of ferretic cast iron let to obtain tensile strength above 500 MPa and elongation approx. 23 %. Precipitation hardening of ductile cast iron efficiently compensates reducing of hardening caused by partial graphitization and spheroidization of pearlitic cementite.
