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.
This standard has been approved for use by agencies of the Department of Defense. This specification covers aluminum-alloy die castings of all compositions. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Current edition approved April 10, G Based on resistance of alloy in standard type salt spray test. 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.
Additions of small amounts of modifiers and grain refining elements or alloys are permitted. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard. Hence the rating for each characteristic is a relative measure of that attribute compared to the same attribute in another alloy. K Rated on lightness of color, brightness and uniformity of clear anodized coating applied in sulphuric acid electrolyte.
Conformance shall be determined by the producer by analyzing samples taken at the time castings are made. The castings shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints or drawings. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Sampling shall be in accordance with Practices E 88 or Eor both. C Limits are in percent maximum unless shown otherwise.
E Ability of molten alloy to? For this reason, it is considered that the only practical method for mechanical property control is proof testing the whole die casting.
Different machines and dies continue to be necessary for die castings and test bars. UNS designations were established in accordance with Practice E G With respect to mechanical properties, alloys A Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

ASTM B85 – 96 Standard Specification for Aluminum-Alloy Die Castings
Generally aluminum die castings are unsuitable for light color anodizing where pleasing appearance is required. Last previous edition approved in as B 85 — However, ratings of 5 may present manufacturing difficulties. Originally approved in The derived SI unit for force is the newton Nwhich is de? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the 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. 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. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
The purchaser shall have the right b5 perform any of the inspections and tests set forth in this speci? Combining values from the two systems may result in non-conformance with the standard.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. In case of dispute, the methods of analysis shall be agreed upon between the producer and the purchaser.
The asmt bibliographic material is provided to assist you with your purchasing decision: It should be thoroughly understood that the data in Table X2. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute. The producer or supplier shall be responsible only for replacement of the rejected castings to the purchaser.
Other methods may be used only when no published ASTM test method is available. D Ability of alloy to withstand stresses from adtm while cooling through hot-short or brittle temperature range. When the location is not speci?

When tension or impact tests are made, the tension test specimen shown in Fig. F Ability satm molten alloy to? The marking shall consist of raised Arabic numerals, and when applicable capital letters, cast integral.
Historical Version s – view previous versions of standard. 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.
