What is BS EN 1780-2 — Chemical symbol-based designation system about?
BS EN 1780-2 is the second part of an international standard that covers the designation system of alloyed aluminum ingots, master alloys, and castings.
BS EN 1780-2 specifies a chemical symbol-based designation system for aluminum alloys and master alloys as specified in the relevant European standards. It applies to ingots for remelting and to castings.
Note 1: A designation system for unalloyed aluminum is specified in EN 576.
Note 2: An alternative numerical designation system is specified in EN 1780-1. Writing rules for chemical composition are specified in EN 1780-3.
Who is BS EN 1780-2 — Chemical symbol-based designation system for?
BS EN 1780-2 on Chemical symbol-based designation system is relevant to:
- Manufacturers of aluminum and aluminum alloys products
- Designers of aluminum and aluminum alloys products
- Metal fabrication Industries
- Metal engineers
- Industries where aluminum and aluminum alloys products are used
- Testing labs for aluminum and aluminum alloys products

Why should you use BS EN 1780-2 — Chemical symbol-based designation system?
Aluminum and aluminum alloys are used in the engineering field in huge amounts, in structures and construction components. Alloys are mostly composed of aluminum and other elements and are proved very important in many sectors like aerospace manufacturing. The designation of aluminum alloys and master alloys based on their chemical symbols is usually followed by numbers indicating the nominal content of the considered alloying element.
BS EN 1780-2 provides you with guidance on the chemical symbol-based designation system for aluminum and aluminum alloys. It gives you the platform on which codification is based.
BS EN 1780-2 explains the rules for the coded designation of aluminum alloys and master alloys, which helps users to understand the general information, and rules for distinguishing between two alloys of similar composition. It also covers information about the special application for master alloys as well as international chemical symbols.
