Standard Specification for Magnesium-Alloy Sand Castings
Standard Specification for Magnesium-Alloy Sand Castings
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
ASTM B80-23: Standard Specification for Magnesium-Alloy Sand Castings defines the requirements for the production and evaluation of magnesium-alloy sand castings. Published by ASTM International, this standard covers chemical composition limits, mechanical property requirements, heat treatment procedures, foundry control methods, inspection protocols, and quality assurance. It is widely used in industries requiring lightweight yet strong components, such as aerospace, automotive, military, and industrial applications. Compliance ensures that castings meet stringent quality and safety expectations, providing reliability in critical end-use environments.
Magnesium-alloy sand castings governed by ASTM B80-23 are ideal for applications where lightweight, high-strength materials are essential. Notable uses include:
