ASTM B595-21

Standard Specification for Materials for Aluminum Powder Metallurgy (PM) Structural Parts

ABSTRACT
This specification covers sintered aluminium structural parts made primarily from aluminum powders to which controlled amounts of master alloys or elemental copper, magnesium, and silicon have been added by blending. Structural parts shall be made by molding and sintering metal powders to produce finished parts conforming to the requirements of this specification. Chemical composition of copper, magnesium, and silicon content, as well as the density of the material shall conform to the requirements specified. Tests for the determination of the mechanical properties such as ultimate tensile strength, tensile yield strength, elongation and apparent Rockwell hardness of the material shall be performed.
SCOPE
1.1 This specification covers aluminum powder metallurgy structural parts made using admixed materials.  
1.2 This specification covers a material designation code that includes the chemical composition of the material, its guaranteed minimum 0.2 % offset yield strength or ultimate tensile strength, and the temper condition of the material.  
1.3 Units—With the exception of density values for which the g/cm3 unit is the industry standard, property values stated in inch-pound units are to be regarded as standard. Values in SI units result from conversion, are only for information, and are not considered standard.  
1.4 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.  
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
