Abstract

Research works presented in the article aim to determine optimal ratio of Mg and Si content in chemical composition of commercial EN-AW 6082 aluminium alloy in order to maximize mechanical properties of this material. Various amounts of Si (in the rage of 0,6-1,2 wt. %) and Mg (0,6-1,1 wt. %) along with 0,4 wt. % of Fe, 0,4 wt. % of Mn and 0,05 wt. % of Ti were metallurgically synthesised with the use of gravity die casting process which allowed to obtain 5 different castings. In the next phase of research works all alloys were subjected to mechanical and electrical properties testing in as cast temper and after performed heat treatment.
