EN 573-1: Numerical Designation System for Wrought Aluminum Alloys
Technical Requirements of EN 573-1
The EN 573-1 standard establishes a unified European marking system for wrought semi-finished products made of aluminum and its alloys. The methodology is based on an international classifier, ensuring transparency when selecting materials for engineering tasks. The system uses a four-digit numerical code that uniquely identifies the chemical composition and physical-mechanical characteristics of the alloy.
The regulation applies to finished metal products and blanks (ingots) intended for further processing by plastic deformation, including forging. EV Group China ensures the supply of aluminum rolled products that fully comply with these international specifications.
EN 573-2: Chemical Nomenclature and Alloy Designations
Scope of EN 573-2
This part of the standard describes the coding of aluminum alloys based on the chemical symbols of elements. This system serves as a supplement to the numerical classification of EN 573-1, allowing engineers to accurately identify the alloying components of an alloy.
The standard covers a wide range of products intended for forging. Exceptions include:
- Casting ingots for remelting;
- Products intended for casting;
- Composite materials containing non-metallic or heterogeneous inclusions;
- Products obtained by powder metallurgy methods.
EN 573-3: Regulation of Chemical Composition of Wrought Alloys
EN 573-3 Specification
EN 573-3 is a key document that defines the permissible percentage content of chemical elements in aluminum alloys. It sets limits for impurities and alloying additives for each grade, which is critical for ensuring the operational reliability of structures. EV Group China strictly monitors the compliance of supplied products with these industry tolerances.
EN 573-4: Classification of Forms and Types of Aluminum Rolled Products
Scope of EN 573-4
The EN 573-4 standard systematizes the geometric forms of products available for industrial production from wrought aluminum. The document directly correlates with the requirements of EN 573-3, providing a technological link between chemical composition and available assortment.
The use of a four-digit numerical designation system in this standard allows for the unification of metal supply orders. Please note that the mention of specific product forms does not override patent rights regarding specialized production technologies.
