ASTM International – Standard References for ASTM B85 / B85M – 18e1
Originally approved in Different machines and dies continue to be necessary for die castings and test bars. Packaging and Package Marking The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute. Generally aluminum die castings are unsuitable for light color anodizing where pleasing appearance is required.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phone asm, faxor service astm.

This standard has been approved for use by agencies of the Department of Defense. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications. L Rated on combined resistance of coating and base alloy to corrosion. Die castings inspected by this method shall be so marked or handled during the? If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Dimensions, Mass, and Permissible Variations Additions of small amounts of modifiers and grain refining elements or alloys are permitted. Combining values from the two systems may result in non-conformance with the standard. UNS designations were established in accordance with Practice E D Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range.
ASTM B85 Grade SC84B
It is the responsibility of the user of this h85 to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Pure materials, recycled materials, and awtm 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.
A rating of 1 gives the best performance, 5 the poorest performance.
The castings shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints or drawings. Combining values from the two systems may result in non-conformance with the standard.
However, ratings of 5 may present manufacturing difficulties. A number in parentheses indicates the year of last reapproval. 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.

The following bibliographic material is provided to assist you asrm your purchasing decision: Characteristics of Die Casting Alloys In considering these ratings, it should be noted that all the alloys have sufficiently good characteristics to be accepted by users and producers of die castings.
ASTM International takes no position respecting the validity of any qstm rights asserted in connection with any item mentioned in this atm. 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.
