The inclusions in remelted aluminum scrap are different than those in primary
metal, as Table 12.1 shows. Scrap inherently has more dirt and oxide in it than pri-
mary metal (Pyrotek, 2006), and the oxide skins generated during melting increase
the inclusion count even more (Altenpohl, 1998). As a result, inclusion removal is
much more important in secondary aluminum production. Remelting of bulky scrap
generates metal with fewer inclusions than remelted UBC or light scrap; the price
of bulky scrap is higher as a result (see Chapter 4). Remelting of high-magnesium
alloys generates a higher inclusion count, due to the g
