Aluminium and aluminium alloys - Designation of alloyed aluminium ingots for remelting, master alloys and castings - Part 3: Writing rules for chemical composition

This part of prEN 1780 specifies the writing rules for chemical composition of unalloyed aluminium, aluminium alloys and master alloys. Writing rules for unalloyed aluminium are specified in prEN 576. It applies to lingots for remelting and to castings. The five-figure numerical and the chemical symbol based designation systems of materials are specified in prEN 1780-1 and prEN 1780-2, respectively.

Aluminium und Aluminiumlegierungen - Bezeichnung von legiertem Aluminium in Masseln, Vorlegierungen und Gussstücken - Teil 3: Schreibregeln für die chemische Zusammensetzung

Dieser Teil von prEN 1780 legt die Schreibregeln für die chemische Zusammensetzung von Aluminiumlegierungen und Vorlegierungen fest. Schreibregeln für unlegiertes Aluminium sind in prEN 576 festgelegt. Er gilt für Masseln und Gußstücke. Die Bezeichnungssysteme für Werkstoffe auf numerischer Basis, bestehend aus 5 Ziffern bzw. auf Basis der chemischen Symbole sind in prEN 1780-1 bzw. prEN 1780-2 festgelegt.

Aluminium et alliages d'aluminium - Systeme de désignation applicable aux lingots pour refusion en aluminium allié, aux alliages-meres et aux produits moulés - Partie 3: Regles d'écriture pour la composition chimique

La présente Norme européenne spécifie les regles d'écriture de la composition des lingots pour refusion en aluminium allié, des alliages-meres et des produits moulés. Les regles d'écriture pour les aluminiums non alliés sont spécifiés dans l'EN 576.
Les systemes de désignation numérique a cinq chiffres et de désignation basée sur les symboles chimiques sont décrits respectivement dans l'EN 1780-1 et l'EN 1780-2.
