Aim of this work was to do divers heat treatment for AlSi12CuMgNi alloy as a temper hardening (artificial ageing) with different temperatures of purpose to acquire the best mechanical properties (breaking limit and creep limit in comparison with required dilatability min. 7 - 8 %). Further aims were to search exchanges in material substructure for several heat conditions, to compare this with reached mechanical values and with influence into form and character of receiving chip on the machining under the same conditions. From heat treatment view and strength properties influence for this Al2Cu3Ni alloy is some important intermetallic compound phase marked as the T phase, what makes precipitates stable in higher temperatures to the 300°C, too. Cu and Mg presence also makes intermetallic compound CuMgAl2, what participates on the strength properties increase after heat treatment.

Keywords: aluminum alloys, mechanical properties, treatment
