What is BS EN 573‑3 - Aluminium and aluminium alloys about?
BS EN 573 is a series of European standards on aluminium and aluminium alloys that discusses the chemical properties and form of wrought products. BS EN 573‑3 is the third part of a series of documents on aluminium and aluminium alloys. BS EN 573‑3 specifies the chemical composition limits of wrought aluminium and wrought aluminium alloys and the 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.
Who is BS EN 573‑3- Aluminium and aluminium alloys for?
BS EN 573‑3 on aluminium and aluminium alloys is relevant to:
- Manufacture of aluminium and aluminium alloys
- Laboratories and research centres
Why should you use BS EN 573‑3- Aluminium and aluminium alloys?
An Aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc. About 85% of aluminium is used for wrought products, for example, rolled plates, foils and extrusions.
BS EN 573‑3 navigates you through the chemical composition limits of wrought aluminium and wrought aluminium alloys and Applications and forms of products.
BS EN 573‑3 exemplifies the required chemical composition that helps you achieve precision in terms of products specification. BS EN 573‑3 provides you with comprehensive information useful throughout the process of production of aluminium and aluminium alloys. In this manner, you can produce high-quality aluminium alloys.
What’s changed since the last update?
BS EN 573‑3:2019 supersedes BS EN 573‑3:2013, which is withdrawn.
CEN/TC 132 has decided to revise this document as follows:
- Addition of the alloy EN AW-2016 in Table 2 and A.2, EN AW-4025 in Tables 4 and A.4, EN AW-6050 in Tables 6 and A.6, EN AW-5018B in Tables 5 and A.5, EN AW-8026 in Table 8 and A.8
- Correction of the alloy EN AW-5449 in Table 5 and EN AW-6064A in Table 6
- Modification of the order of alloys to conform with the Aluminium Association System
