(Amendment)Aluminium and aluminium alloys - Chemical composition and form of wrought products - Part 3: Chemical composition and form of products
- Abstract
This document specifies the chemical composition limits of wrought aluminium and wrought aluminium alloys and form of products.
NOTE The chemical composition limits of aluminium and aluminium alloys specified herein are completely identical with those registered with the Aluminium Association, 1525, Wilson Boulevard, Suite 600, Arlington, VA 22209, USA, for the corresponding alloys.

SIST EN 573-3:2026/oprA1:2026 is a CEN draft amendment to EN 573-3:2026 for aluminium and aluminium alloys. It updates the chemical composition limits and product-form listing for wrought products, adding an entry for EN AW-5050D. The scope note says the composition limits are identical to those registered with the Aluminium Association for the corresponding alloys.
What does SIST EN 573-3:2026/oprA1:2026 specify?
SIST EN 573-3:2026/oprA1:2026 specifies changes to EN 573-3:2026 in two places: the chemical composition limits in Clause 4 and the product-form information in Annex A. The document is organized as a European foreword plus two amendment clauses.
| Clause / annex | What it covers |
|---|---|
| Clause 4, Table 5 | Chemical composition limits for aluminium alloys in the 5000 series; this amendment adds EN AW-5050D. |
| Annex A, Table A.5 | Form of products for the 5000 series; this amendment adds EN AW-5050D. |
What are the key requirements of SIST EN 573-3:2026/oprA1:2026?
SIST EN 573-3:2026/oprA1:2026 adds one alloy designation to the chemical-composition table and the matching product-form table. In practice, that means users can specify, check, and document EN AW-5050D against the same standard structure used for the rest of the 5000 series.
- Clause 4, Table 5 adds EN AW-5050D to the 5000 series, Al Mg family. This matters because the alloy now has a defined composition row for specification and analytical checking.
- The table identifies the alloy as EN AW-Al Mg1,5(D). That gives buyers, producers, and laboratories the standardized designation they should use when naming the alloy.
- Annex A, Table A.5 adds EN AW-5050D to the product-form matrix. This matters because it links the alloy to the forms in which it is covered by the standard.
- The scope note states that the chemical composition limits are identical to those registered with the Aluminium Association for the corresponding alloys. In practice, this helps keep alloy identification aligned across different reference systems.
- The amendment focuses on two linked checks: chemistry and form of products. That is what users need when comparing test results, writing purchase specifications, or confirming that a product form is covered.
What terms does SIST EN 573-3:2026/oprA1:2026 define?
- CEN - The European Committee for Standardization, which publishes the draft amendment.
- CEN/TC 132 - The technical committee for aluminium and aluminium alloys that prepared the document.
- wrought products - Aluminium products made by shaping the material, which is the product family covered by the standard.
- chemical composition limits - The allowed element ranges used to define and control an alloy designation.
- form of products - The product-form categories listed in Annex A, used to show which forms are covered.
- EN AW-5050D - The alloy designation added by this amendment, with its own composition row and product-form entry.
Who uses SIST EN 573-3:2026/oprA1:2026?
SIST EN 573-3:2026/oprA1:2026 is used by material specifiers, aluminium producers, fabricators, buyers, quality managers, and test laboratories. They use it when they need to state the alloy designation, verify chemical analysis results, or confirm whether a wrought product form is covered by the standard. It is also relevant when aligning internal material specifications with a European designation.
What changed in SIST EN 573-3:2026/oprA1:2026 from the previous edition?
SIST EN 573-3:2026/oprA1:2026 modifies EN 573-3:2026 by adding EN AW-5050D to Table 5 in Clause 4 and to Table A.5 in Annex A. Those are the changes stated in the amendment.
Which standards are used with SIST EN 573-3:2026/oprA1:2026?
EN 573-3:2026 is the base European Standard that SIST EN 573-3:2026/oprA1:2026 modifies. Users read this draft amendment together with EN 573-3:2026 because the amendment changes Clause 4 and Annex A of that document.
What does the SIST EN 573-3:2026/oprA1:2026 document contain?
SIST EN 573-3:2026/oprA1:2026 contains a European foreword and two amendment clauses. Clause 1 revises the chemical-composition table in Clause 4, and Clause 2 revises the product-form table in Annex A. The practical content is in Table 5 and Table A.5, which connect alloy designation to permitted chemistry and product-form coverage.
The amendment does not reproduce a full new standard; it updates specific tables in the existing one. For users, the important part is the link between the alloy row and the forms of wrought products to which it applies.
