This European Standard specifies a chemical symbol based designation system for aluminium alloys and master alloys as specified in the relevant European Standards. It applies to ingots for remelting and to castings. A designation system for unalloyed aluminium is specified in EN 576. An alternative numerical designation system is specified in prEN 1780-1. Writing rules for chemical composition are specified in prEN 1780-3.
