Aluminium and aluminium alloys - Designation of alloyed aluminium ingots for remelting, master alloys and castings - Part 1: Numerical designation system
This European Standard specifies a five-figure numerical designation system for aluminium alloys and master alloys as specified in the relevant European Standards. It applies to ingots for remelting and to castings for all applications including aerospace.
A designation system for unalloyed aluminium is specified in prEN 576. An alternative numerical designation system is specified in prEN 1780-1. Writing rules for chemical composition are specified in prEN 1780-3.
An alternative chemical symbol based designation system is specified in prEN 1780-2. The writing rules for chemical composition are specified in prEN 1780-3.
Aluminium und Aluminiumlegierungen - Bezeichnung von legiertem Aluminium in Masseln, Vorlegierungen und Gussstücken - Teil 1: Numerisches Bezeichnungssystem
Dieser Teil von prEN 1780 legt ein aus fünf Ziffern bestehendes numerisches Bezeichnungssystem für Aluminiumlegierungen und Vorlegierungen fest. Ein Bezeichnungssystem für unlegiertes Aluminium ist in prEN 576 festgelegt. Er gilt für Masseln und Gußstücke für alle Anwendungsgebiete, einschließlich Luft- und Raumfahrt. Ein alternatives Bezeichnungssystem, basierend auf chemischen Symbolen, ist in prEN 1780-2 festgelegt. Schreibregeln für die chemische Zusammensetzung sind in prEN 1780-3 festgelegt.
