Abstract Scope |
Recycled aluminium cans are usually used for the production of new cans and other valuable aluminium products such as engine blocks, building facades, bicycles, menu trays, etc. This study investigates the effect of 0-2% zinc addition on the microstructure, corrosion resistance and mechanical properties of recycled aluminium beverage cans. Metallographic examination of the samples showed considerable grains refinement due to the addition of zinc. The results of the potentiodynamics test using 1M HNO3 revealed increase in the corrosion resistance of the samples with increase in zinc addition. The mechanical tests showed a drop in the Vickers-hardness value at 1% zinc addition. However, further increase in zinc improved the hardness of the sample. The UTS increased significantly with the addition of zinc but there was a drop to about 97.2 MPa at 0.75 wt. % zinc. The ductility and impact energy of the samples generally increased with increase in zinc addition. |
