This specification applies to additively manufactured AlSi10Mg parts using powder bed fusion such as laser melting. The parts produced by these processes are commonly used in applications that require mechanical properties similar to or exceeding those of cast aluminum products of equivalent alloys. The requirements established by this specification cover ordering information, manufacturing plan, chemical composition of feedstock (pre-alloyed metal powder such as copper, iron, magnesium, manganese, nickel, silicon, zinc, titanium, lead, tin, and aluminum), processing, post build chemical composition, microstructure, mechanical properties (minimum tensile properties), thermal processing, retests, inspection, certification, product marking and packaging, quality program, and numerical limits.
1.1 This specification covers additively manufactured AlSi10Mg (similar to DIN EN 1706:2013-12 EN AC-43000) parts using powder bed fusion such as laser melting. The parts produced by these processes are used typically in applications that require mechanical properties similar to or exceeding those of cast aluminum products of equivalent alloys. Parts manufactured to this specification are often, but not necessarily, post processed via machining, grinding, electrical discharge machining (EDM), polishing, and so forth to achieve desired surface finish and critical dimensions.
1.2 This specification is intended for the use of purchasers or producers, or both, of additively manufactured AlSi10Mg parts for defining the requirements and ensuring part properties.
1.3 Users are advised to use this specification as a basis for obtaining parts that will meet the minimum acceptance requirements established and revised by consensus of the members of the committee.
1.4 User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which may include, but are not limited to, those listed in Supplementary Requirements S1–S16.
1.5 The values stated in SI units are to be regarded as the standard. Other units are included only for informational purposes.
1.6 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.
1.7 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.
