Alloys are mostly composed of aluminium and other elements and are proved very important in many sectors like aerospace manufacturing. BS EN 1780-1 is a part of an international multi-series standard that covers the composition of alloyed aluminium ingots, master alloys, and castings.
BS EN 1780-1 specifies a five-figure numerical designation system for aluminium alloys and master alloys as specified in the relevant European Standards. BS EN 1780-1 applies to ingots for remelting and castings for all applications including aerospace.
Note 1: A designation system for unalloyed aluminium is specified in EN 576.
Note 2: An alternative chemical symbol-based designation system is specified in EN 1780-2.
Note 3: The writing rules for chemical composition are specified in EN 1780-3.
BS EN BS EN 1780-1 on the designation of aluminium ingots is useful for:
Aluminium and aluminium alloys are used in the engineering field in huge amounts, in structures and construction components. The designation of aluminium 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 1780-1 provides a basis of codification that depict a user-friendly idea of the numerical designation system. BS EN 1780-1 provides users with a five-figure designation system that acknowledges the designation system of the alloys. The guidelines in BS EN 1780-1 help you perceive the designation of aluminium ingots enabling users to verify their compliance with the global standards and provide a superior quality product to their customers.
