The paper presents a study of the influence of iron impurities in zinc and its alloys on their basic electrochemical properties. The research investigates different alloying elements and their effect on the electrochemical properties, especially the coefficient of use efficiency (CUE).

The characteristic of the elements present in the primary aluminum at electrolytic method of production is given. Based on elemental analysis of aluminum on regulated and unregulated impurities, with accordance of their initial content and effect on operational characteristics of cast billets, in this paper we describe groups of useful elements, neutral and harmful impurities at production of materials for functional purposes (sacrificial, composite, electrotechnical, etc.).
