\u0130ster elektrolitik ham al\u00fcminyum s\u0131v\u0131s\u0131 ister yeniden eritilmi\u015f al\u00fcminyum s\u0131v\u0131s\u0131 olsun, hepsi al\u00fcmina ve hidrojen i\u00e7erir. Bu iki metalik olmayan kirlilik, al\u00fcminyumun proses performans\u0131n\u0131, fiziksel \u00f6zelliklerini ve mekanik \u00f6zelliklerini etkileyen ba\u015fl\u0131ca kirliliklerdir. Bu nedenle, erimi\u015f al\u00fcminyumun ar\u0131t\u0131lmas\u0131 esas olarak bu iki kirlili\u011fi gidermeyi ama\u00e7lamaktad\u0131r.
