BS EN 1753:2019 pdf download.Magnesium and magnesium alloys- Magnesium alloy ingots and castings
1 Scope
This document specifies the grades and the corresponding requirements for cast alloyed magnesium materials.
This document specifies two groups of cast magnesium alloy grades by a classification based on the chemical composition. The first group deals with grades for magnesium alloy ingots. The second group deals with grades for magnesium alloy castings.
This document also specifies mechanical properties measured on test pieces machined from cast samples.
This document does not cover technical delivery conditions for magnesium alloy castings (see EN 1559-1 [7] and EN 1559-5 [8]).

6 Manufacture
The method of producing magnesium alloy ingots and castings shall be left to the discretion of the manufacturer who shall ensure that the requirements of this document are met for the material grade specified in the order. All agreements between the manufacturer and the purchaser shall be made by the time of the acceptance of the order.
7 Requirements
7.1 Chemical composition The chemical composition of magnesium alloy ingots shall conform to the requirements for the appropriate material grade given in Table 1. The chemical composition of magnesium alloy castings shall conform to the requirements for the appropriate material grade given in Table 2. If not otherwise specified in the enquiry and order, the chemical composition of the ingot or casting shall relate to that of the cast samples taken from the melt at the time of pouring. NOTE 1 For additional information regarding the manganese and iron contents, see Annex B. NOTE2 For additional information regarding the maximum content of alloying and trace elements in ingots and castings, see Annex C.
