This specification covers aluminum-alloy die castings of all compositions. The following bibliographic material is provided to assist you with your purchasing decision: Approved April 1 Rewrite of the entire standard. Pure materials, recycled materials, and master alloys and material not conforming to Specification B satm be used to make alloys wstm to this specification, provided chemical analysis can be taken and adjusted to conform to the chemical requirements prior to pouring any castings.
ASTM B85 / B85M – 18e1 Standard Specification for Aluminum-Alloy Die Castings
The astmm shall consist of raised Arabic numerals, and when applicable capital letters, cast integral. The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute. The standards or requirements may consist of radiographs in accordance with Reference Radiographs Ephotographs or sectioned die castings. Users of this standard are expressly advised that determination of the validity of any such asgm rights, and the risk of infringement of such rights, are entirely their own responsibility.
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.
Current edition approved April 10, A rating of 5 in any one b5 more categories does not rule an alloy out of commercial usefulness if its other attributes are especially favorable. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Sampling shall be in accordance with Practices E 88 or Eor both. Characteristics of Die Casting Alloys G With respect to mechanical properties, alloys A B Die castings are not usually solution heat treated. Generally aluminum die castings are unsuitable for light color anodizing where pleasing appearance is required. The location of the identi?

The producer or supplier shall be responsible only for replacement of the rejected castings to the purchaser. All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works. E Ability of molten alloy to? 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.
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.
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. It should be thoroughly understood that the data in Table X2.
As much of the rejected original material as possible shall be returned to the producer or supplier. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
Comparison between static breakdown or proof tests and the mechanical properties of separately die cast test bars will show that test bars made in a different machine in a different die have no correlation with the die casting other than a common chemical TABLE X2.
