A significant number of different metals are present in aluminum alloy scrap and waste. Secondary cast alloys, made by recycling from waste, have as the main impurity Fe. Fe reduction is a very economically technologically expensive process therefore there growing interest researching such materials. Moreover, higher content leads to formation brittle Fe-rich phases, leading faster propagation fracture castings. Therefore, this study reflected on secondary with concentration research their effect phase (in needle; plate-like form) This confirms increasing amount needle phases melt The large cleavage fractures surfaces. Although increased, experimental results show low changes properties all melts.
