It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications. Unless otherwise specified, only aluminum alloy conforming to the requirements of Specification B or producer’s foundry scrap shall be used in the remelting furnace from which molten metal is taken for pouring directly into castings.
Packaging and Package Marking Unalloyed aluminum contains a minimum of Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
This standard is subject to revision at any time by the responsible technical committee and must asym reviewed astk
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. A rating of 1 gives the best performance, 5 the poorest performance. Hence the rating for each characteristic is a relative measure of that attribute compared to the same attribute in another alloy. Marking for shipment shall be in accordance with Fed.
Additions of small amounts of modifiers and grain refining elements or alloys are permitted. Die castings are not generally gas or arc welded or brazed. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard. The standards n85 requirements may consist of radiographs in accordance with Reference Radiographs Ephotographs or sectioned die castings.

E Ability of molten alloy to? The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute. Pure sstm, recycled materials, and master alloys and material not conforming to Specification B may be used to make alloys conforming to this specification, provided chemical analysis can be taken and adjusted to conform to the chemical requirements prior to pouring any castings. D Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range.

g85 Low temperature aging treatments may be used for stress relief or dimensional stability. The producer or supplier shall be responsible only for replacement of the rejected castings to the purchaser. For the products described, mechanical property limits for the respective size ranges are based on the analyses of at least data from standard production material with no more than ten data from a given lot.
Combining values from the two systems may result in non-conformance with the standard.
