Some of the alloys referenced in this s
22、tandard can be the subject of a patent or of patent applications and their listing herein is not to be construed in any way as the granting of a licence under such patent rights. 1 Scope This European Standard specifies the chemical composition of magnesium alloy ingots. It also specifies the chemic
23、al composition of magnesium alloy castings. It also specifies the mechanical properties of separately cast samples of these alloys (see clause 6). By agreement, it also specifies the mechanical properties of magnesium alloy castings determined from samples cut from a casting. 2 Normative references
24、This standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications
