Product catalog summary

Product Format and Characteristics

The document specifies aluminum alloys provided as rolled sheets and strips in laminate form, designed for various industrial applications requiring precise mechanical and chemical properties.

Aluminum Alloy Series and Chemical Composition

Aluminum alloys are categorized by series based on primary alloying elements, each with defined chemical composition limits to ensure performance and conformity.

Series 1000 – Pure Aluminum (Al)

High purity aluminum with 99.00% to 99.99% Al content.
Strict limits on minor elements such as Si, Fe, Cu, Mn, Mg, Cr, Ni, Zn, Ti, Ga, and V.
Special notes on calculation of aluminum content depending on refining and welding filler wire restrictions.

Series 2000 – Aluminum-Copper Alloys (Al Cu)

Copper content typically 3-6%, with additions of Mg, Mn, Pb, Bi, Ni, Zn, Ti, and Zr for enhanced properties.
Includes alloys like EN AW-2001, 2011, 2024, 2219, and 2618A.
Notes on limits for Pb, Bi, Sn, and welding filler wire usage.

Series 3000 – Aluminum-Manganese Alloys (Al Mn)

Manganese content ranges from 0.2% to 1.5%, often combined with Mg and Cu.
Alloys include EN AW-3003, 3004, 3105, among others.
Welding filler wire limits and Pb presence noted.

Series 4000 – Aluminum-Silicon Alloys (Al Si)

Silicon content varies from ~1% to over 12%, combined with Mg, Fe, Cu, Mn, Cr, Ni, Zn, Ti, Ga, and V.
Alloys such as EN AW-4045, 4047A, and 4032.
Welding filler wire restrictions and Bi presence highlighted.

Series 5000 – Aluminum-Magnesium Alloys (Al Mg)

Magnesium content from ~0.5% to 6%, with Mn, Cr, Fe, Cu, Ni, Zn, Ti, Ga, and V.
Includes EN AW-5005, 5052, 5083, 5182, and others.
Notes on Mn + Cr limits, Pb presence, and welding filler wire restrictions.

Additional Series (5000, 6000, 7000) Overview

Series	Main Alloying Elements	Typical Applications	Key Notes
5000 Series	Mg (0.5-5.5%), Mn, Cr, Zr	Marine, automotive, structural	Good corrosion resistance, weldability
6000 Series	Mg, Si, Cu, Mn	Architectural, transport, general engineering	Good strength and corrosion resistance
7000 Series	Zn (4-8%), Mg, Cu, Zr, Ti	Aerospace, high-strength structural	High strength, sensitive to corrosion

Notes and Quality Control

"Others" elements refer to unspecified metallic elements with strict individual and total content limits to ensure conformity.
Aluminum content is calculated as 100% minus the sum of other metallic elements, with precision depending on refining processes.
Specific maximum limits exist for elements such as Pb, Bi, Sn, Be, especially relevant for welding applications.
Some alloys permit additions of Zr and Ti to enhance mechanical properties, subject to combined maximum limits.

Critical Parameters and Limitations

Strict control of elemental composition is essential for alloy identification and performance.
Trace elements in "Others" must not exceed specified limits to avoid non-conformance.
Special attention to elements affecting weldability and corrosion resistance, including Be, Pb, Bi, and Zr.
Manufacturing tolerances allow composition variations within specified ranges.

Recommendations and Best Practices

Manufacturers should conduct chemical analyses to verify compliance with alloy specifications.
Purchasers must confirm alloy conformity, particularly regarding trace elements in "Others".
Supplier-purchaser agreements may be necessary for certain element limits in specialized alloys.

Conclusion

This document is a comprehensive reference for chemical composition and technical characteristics of aluminum alloy series used in rolled sheet and strip laminate products. Adherence to these specifications is critical for manufacturers, purchasers, and quality control personnel to ensure material performance and compliance.
