摘要

In recent decades an increasingly large fraction of the world's supply of wrought aluminium alloys has come from the aluminium scrap recovered from industrial waste and discarded consumer items. The reason for that is the creation of an additional net increase in added value during the production of wrought alloys achieved through the consumption of inexpensive raw materials. In other words, the common way of creating new added value inside the casting house is in substituting as far as possible costly and energy-intensive primary aluminium and the alloying elements by cheaper and commonly available sources of aluminium alloys - preferably lower grades of scrap.
