What is BS EN 1780-3 —Rules for chemical composition about?

BS EN 1780-3 is the third part of an international standard that covers the composition of alloyed aluminum ingots, master alloys, and castings.

BS EN 1780-3 specifies the writing rules for the chemical composition of alloyed aluminum ingots for remelting, master alloys and castings.

Note 1: Writing rules for unalloyed aluminum are specified in EN 576.

Note 2: The five-figure numerical and the chemical symbol-based designation systems of materials are specified in EN 1780-1 and EN 1780-2, respectively.

Who is BS EN 1780-3 —Rules for chemical composition for?

BS EN 1780-3 on Rules for chemical composition 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
Regulatory authorities
Quality control personnel

Why should you use BS EN 1780-3 —Rules for chemical composition?

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 1780-3 provides you with guidance on rules for writing the chemical composition of aluminum and aluminum alloys. It gives you the designations for aluminum and aluminum alloys, a platform on which codification is based.

BS EN 1780-3 explains the sequence of elements for the indication of the chemical composition for master alloys and alloyed aluminum ingots which helps users to acknowledge the remelting and castings of the alloys. It also talks about rounding rules for the chemical composition of alloys which help users to verify their compliance with the global standards.
