CEN/TC 132/WG 1 - Liquid metal, unalloyed and alloyed ingots

This EN specifies the requirements for grades of refined aluminium and other unalloyed aluminium in the form of ingots for remelting. It specifies the designations for these grades, the conditions in which they are produced, their properties and the marks by which they are identified.

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.

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.

This European Standard specifies a chemical symbol based designation system for aluminium alloys and master alloys as specified in the relevant European Standards. It applies to ingots for remelting and to castings.
A designation system for unalloyed aluminium is specified in EN 576. An alternative numerical designation system is specified in prEN 1780-1. Writing rules for chemical composition are specified in prEN 1780-3.

This European Standard specifies the requirements for grades of master alloys produced by melting and intended for addition to a melt to adjust composition and/or to control impurities and/or to control the as-cast structure. It specifies the classification and designation applicable to these grades, the conditions in which they are produced, their properties and the marks by which they are identified.

This European Standard specifies the requirements for the delivery in liquid metal of unalloyed aluminium or aluminium alloys.

This European Standard defines the requirements for grades of alloyed aluminium ingots intended for remelting. It specifies the classifications and designations applicable to these grades, the conditions in which they are produced, their properties and the marks by which they are identified.

This European Standard specifies the requirements for grades of unalloyed and refined aluminium ingots intended for remelting. It specifies the classifications and designations applicable to these grades, the conditions in which they are produced, their properties and the marks by which they are identified.

This part of prEN 132/14 specifies a code of designation applicable to unalloyedaluminium, aluminium alloys and master alloys as specified in the relevant European Standards. It is a descriptive code based primarily on chemical symbols. It applies to ingots for remelting and to castings. An alternative numerical system is specified in EN 1780-1. Writing rules for chemical composition are described in EN 1780-3.

This part of EN 132/14 describes a five-figure numerical designation system of unalloyed aluminium, aluminium alloys and master alloys. It applies to ingots for remelting and to castings and applies to both CEN and AECMA alloys. An alternative chemical symbol based designation system is described in EN 1780-2. Writing rules for chemical composition are described in EN 1780-3.

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