Sekt\u00f6r\u00fcm\u00fczde kullan\u0131lan hammaddeye al\u00fcminyum k\u00fcl\u00e7e denmektedir; ulusal standarda (GB\/T 1196-2008) g\u00f6re bu hammaddeye \u201cyeniden eritme ama\u00e7l\u0131 al\u00fcminyum k\u00fcl\u00e7e\u201d denmesi gerekse de, herkes \u201cal\u00fcminyum k\u00fcl\u00e7e\u201d ifadesine al\u0131\u015fm\u0131\u015ft\u0131r.

\nAl\u00fcminyum k\u00fcl\u00e7eler end\u00fcstriyel uygulamalara girdikten sonra, iki ana kategoriye ayr\u0131l\u0131r: d\u00f6k\u00fcm al\u00fcminyum ala\u015f\u0131mlar\u0131 ve \u015fekillendirilmi\u015f al\u00fcminyum ala\u015f\u0131mlar\u0131.
\nAl\u00fcminyum d\u00f6k\u00fcm ve al\u00fcminyum ala\u015f\u0131m\u0131, d\u00f6k\u00fcm y\u00f6ntemleriyle \u00fcretilen al\u00fcminyum d\u00f6k\u00fcm par\u00e7alard\u0131r.

\nUlusal standartlara g\u00f6re, yeniden eritmeye y\u00f6nelik al\u00fcminyum k\u00fcl\u00e7eler kimyasal bile\u015fimlerine g\u00f6re 8 s\u0131n\u0131fa ayr\u0131l\u0131r; bunlar Al99.90, Al99.85, Al99,70, Al99,60, Al99,50, Al99,00, Al99,7E ve Al99,6E olarak s\u0131n\u0131fland\u0131r\u0131l\u0131r (Not: Al'den sonraki say\u0131 al\u00fcminyum i\u00e7eri\u011fini g\u00f6sterir).
\nBaz\u0131lar\u0131 buna \u201cA00\u201d al\u00fcminyum der; bu asl\u0131nda safl\u0131\u011f\u0131 99,7% olan al\u00fcminyumdur. Londra piyasas\u0131nda ise \u201cstandart al\u00fcminyum\u201d olarak adland\u0131r\u0131l\u0131r.<\/p>\n
Hammaddesi olarak saf al\u00fcminyum ve geri d\u00f6n\u00fc\u015ft\u00fcr\u00fclm\u00fc\u015f al\u00fcminyum kullan\u0131l\u0131r; ayr\u0131ca uluslararas\u0131 standartlara veya \u00f6zel gereksinimlere g\u00f6re silikon (Si), bak\u0131r (Cu), magnezyum (Mg), demir (Fe) gibi di\u011fer elementler eklenir\u2026 Bu, saf al\u00fcminyumun d\u00f6k\u00fclebilirli\u011fini ve kimyasal \u00f6zelliklerini iyile\u015ftirir ve ala\u015f\u0131m\u0131n fiziksel \u00f6zelliklerindeki eksiklikleri giderir.<\/p>\n
