ABSTRACT
This specification covers magnesium-alloy sand castings. The castings shall conform to the chemical composition limits specified. The castings may be subjected to such heat treatment as deemed necessary to produce material that will conform to the requirements specified. Heat treatment shall be performed on the whole casting and never on a portion. Foundry control shall consist of examination of the castings by radiographic or other approved methods for determining internal discontinuities until the gating, pouring, and other foundry practices have been established to produce castings meeting the quality standards. The tension test specimens representing the castings shall conform to the requirements.
SCOPE
1.1 This specification covers magnesium-alloy sand castings designated as shown in Table 1.
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values in parentheses are provided for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM B557-15(2023)(Test Method)
Standard Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products

SIGNIFICANCE AND USE
4.1 Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances.  
4.2 The results of tension tests of specimens machined to standardized dimensions from selected portions of a part or material may not totally represent the strength and ductility properties of the entire end product or its in-service behavior in different environments.  
4.3 These test methods are considered satisfactory for acceptance testing of commercial shipments and have been used extensively in the trade for this purpose.
SCOPE
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8, which cover the tension testing of all metallic materials.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: Foil is sheet metal less than 0.0079 in. thick. There is an overlap in the thickness range 0.006 to 0.0079 in. defined for foil and sheet. Sheet products in this thickness range are supplied to sheet product specifications and foil products in this thickness range are supplied to foil product specifications. Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material.
Note 2: A complete metric companion to Test Methods B557 has been developed—Test Methods B557M; therefore, no metric equivalents are presented in these test methods.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SCOPE
1.1 These test methods cover the tension testing of wrought and cast aluminum- and magnesium-alloy products, with the exception of aluminum foil,2 and are derived from Test Methods E8M, which cover the tension testing of all metallic materials.
Note 1: These metric test methods are the equivalents of those in Test Methods B557, and are compatible in technical content except for the requirement of longer gage lengths for round specimens.
Note 2: Foil is sheet metal less than 0.20 mm thick. There is an overlap in the thickness range 0.15 mm to 0.20 mm defined for foil and sheet. Sheet products in this thickness range are supplied to sheet product specifications and foil products in this thickness range are supplied to foil product specifications. Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Standard Practice for Codification of Unalloyed Magnesium and Magnesium-Alloys, Cast and Wrought

ABSTRACT
This practice provides a system for the codification of unalloyed magnesium and magnesium alloys in the cast and wrought forms. Code designations shall be based on their chemical composition limits. For alloys, designations shall consist of not more than two letters representing the alloying elements specified in the greatest amount, followed by the respective percentages and a serial letter. The letters that represent the alloying elements are: A for aluminum; C for copper; E for rare earths; J for strontium; K for zirconium; L for lithium; M for manganese; Q for silver; S for silicon; T for tin; V for gadolinium; W for yttrium; and Z for zinc. For unalloyed metals, designations shall consist of the specified minimum purity, followed by a serial letter. For both cases, the full name of the base metal precedes the designation, but is omitted for brevity when the base metal being referred to is obvious.
SCOPE
1.1 This practice provides a system for designating unalloyed magnesium and magnesium-alloys that have been used commercially since 1952, and thus is intended to be the registration source for unalloyed magnesium and magnesium-alloys. A record of designations along with the established compositions is given in Table 2.  
1.2 The equivalent Unified Numbering System (UNS) alloy designations shown in the appendixes are in accordance with Practice E527.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Magnesium-Alloy Forgings

ABSTRACT
This specification covers UNS M11311, M11610, M11800, or M16600 magnesium alloy forgings. The conformance of each material to the required chemical composition can be determined using any suitable method of chemical analysis. Samples for chemical analysis should be taken when the ingots are poured or from the finished or semi-finished products by drilling, sawing, milling, turning, or clipping. The variations in testing speed do not seriously affect the obtained tensile property values. However, care must be exercised so that the testing speed does not exceed the ability of the equipment to function satisfactorily. Unless specified, forgings should be chrome pickled before shipment.
SCOPE
1.1 This specification covers magnesium alloy forgings designated as shown in Table 1. (A) Limits are in weight percent maximum unless shown as a range or stated otherwise.(B) These alloy designations were established in accordance with Practice B951.(C) Includes listed elements for which no specific limit is shown.  
1.2 The values stated in inch-pound units are the standard. The SI values in parentheses are provided for information only.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
