European foreword

This document (EN 1676:2020) has been prepared by Technical Committee CEN/TC 132 “Aluminium

and aluminium alloys”, the secretariat of which is held by AFNOR.

This European Standard shall be given the status of a national standard, either by publication of an

identical text or by endorsement, at the latest by October 2020, and conflicting national standards shall

be withdrawn at the latest by October 2020.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on

standardized products under reasonable and not discriminatory conditions, then this product shall be

removed from the corresponding standard.
This document supersedes EN 1676:2010.

Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 23

“Revision of EN 1676 and EN 1706” to revise EN 1676:2010.
In comparison with EN 1676:2010, the following significant changes were made:
a) In Table 1, the following alloys were deleted:
1) EN AB-21200 [EN AB-Al Cu4MnMg];
2) EN AB-43100 [EN AB-Al Si10Mg(b)].
b) In Table 1, the following new alloys were added:
1) EN AB-42300 [EN AB-Al Si7(Mg)];
2) EN AB-42400 [EN AB-Al Si7MnMg];
3) EN AB-44600 [EN AB-Al Si10Mn];
4) EN AB-45600 [EN AB-Al Si7Cu1Mg0,6];
5) EN AB-47200 [EN AB-Al Si12(Fe)];
6) EN AB-48200 [EN AB-Al Si15Cu3MgFe].
c) In Table 1, the maximum limit for lead was reduced to 0,29 %.

d) In Table 1, the chemical composition limits of the alloys EN AB-43000 [EN AB-Al Si10Mg], EN AB-

43300 [EN AB-Al Si9Mg] and EN AB-51300 [EN AB-AlMg5] were modified.
e) In Table 1, footnotes were added and modified.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the

following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

structure, samples, delivery details, etc.
5 Requirements
5.1 Production and manufacturing processes

Unless otherwise specified in the order document, the production and manufacturing processes shall be

left to the discretion of the producer.

Unless it is explicitly stated in the order document, no obligation shall be placed on the manufacturer to

use the same processes for subsequent and similar orders. However, the supplier should inform the

purchaser of any change that could affect the quality of the ingots or the final products.

5.2 Quality control

The supplier shall be responsible for carrying out all inspection and tests required by the relevant

European Standard and/or the particular specification, prior to shipment of the product. If the

purchaser wishes to inspect the product at the supplier's works, he shall stipulate this at the time of

placing the order.
5.3 Chemical composition

Each grade of alloyed aluminium ingot for remelting shall be in accordance with the designations and

chemical composition specified in Table 1.
NOTE For unalloyed aluminium ingots, see EN 576.

For alloys that are not in Table 1, the writing rules for designations and chemical compositions, as

specified in EN 1780-1, EN 1780-2 and EN 1780-3, shall be applied.

If the purchaser requires content limits for elements not specified in this document, these limits shall be

stated on the order document, after agreement between supplier and purchaser.
