Description

As regards the mechanical properties of annealed aluminum sheets, the percentage of virgin ingots in charge is seemed to give extremely an important effect. The more it decreases, the mechanical properties decrease and in higher percentage of return scrap in charge its tendency becomes severe.<br>By the results of study that was made on from 99.6 to 99.8 percent purity of aluminum, the more percentage of return scrap increases, the more the tensile strength and elongation decrease together and in the percentage of return scrap until 30 percent those decrement is rapid and then after it becomes slow.<br>There results are seemed to show that aluminum oxide in its melt is most effective at all. As its proof, a recovery of mechanical properties has recognized. In melting process of the melt of return scrap only, holding-treatment at 800°C have recovered its mechanical properties to the nearly same value of charge of 10 percent of return scrap.
