Impact of Remelting on ZnAl4Cu3 Alloy with Addition of Cd on Selected Technological and Mechanical Properties

One of the main objectives in order to increase economic efficiency foundries is determine ratio scrap material which can be used further manufacture. This factor important for determining final prices products and their competitiveness, given that zinc on world markets have increased significantly recent years. article deals with possibilities remelting foundry alloy ZnAl4Cu3 also evaluates effect cadmium selected properties. The goal provide a comprehensive view influence these two factors mechanical properties, casting microstructure. An part research point out combined factors. results experiments confirmed an addition 3 wt.% Cd has significant impact technological Fluidity values compared Cd-free by 22.4%. In terms tensile strength was most visible, decrease average 25 MPa.
