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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers sintered aluminum structural parts made primarily from aluminum powders to which controlled amounts of master alloys or elemental copper, magnesium, and silicon have been added by mixing.

1.2 This specification covers the following variables:

1.2.1 Composition—Depending upon levels of copper, magnesium, and silicon content, two grades, and

1.2.2 Density—Type.

1.3 Parts ordered to this specification will be in one of the following conditions:

1.3.1 As-sintered,

1.3.2 As-repressed for additional density, or

1.3.3 All other conditions plus heat treated.

1.4 With the exception of the values for density, for which the use of the gram per cubic centimeter unit is long-standing industry practice, the values stated in SI units are to be regarded as the standard.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
