The designation for alloys shall consist of a prefix character “M”, which represents magnesium, and not more than three capital letters representing the alloying elements specified in the greatest amount, arranged in order of decreasing percentages, or in alphabetical order if of equal percentages, followed by the respective percentages rounded off to whole numbers and a serial letter in lower case. The letters used to represent the alloying elements shall be those in Table 1. The third letter is used when the third largest amount of element is above or equal to 1 wt.%. If the third and fourth largest amount of elements are above or equal to 1, the higher amount of elements is taken; if of equal percentage, the third letter is decided by the producer who developed the alloy. Details of heat treatments are given in Annex C. 4.3 Designations of product form The following symbols shall be used for product form: — B: bars and solid sections; — T: tubes and hollow sections; — F: forgings; — P: plate and sheet. 4.4 Designation for ordering EXAMPLE An order for magnesium bars, conforming to this document, of magnesium alloy MAZ31a, delivered in the asfabricated condition (F) is as follows: ISO 3116...
