Remelting and refining modes in advanced recycling of wrought aluminium alloys, Part II

摘要

Because of high cost and shortages of raw materials (primary aluminium and clean scrap), the main challenge facing producers of wrought aluminium alloys and semis are:rn1. running production with alternative, cost-effective sources of aluminiumrn2. with sources of metal which are more easily available.rnAccording to the general estimation that between 3 to 10% of LME is the average amount of new added value achieved by contaminated scrap remelting, consumption of low grade scrap, which is already frequently practised by producers of cast alloys, is also being increasingly introduced by remelters.
