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 astk. Pure materials, 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.
Combining values from the two systems may result in non-conformance with the standard. A number in parentheses indicates the year of last reapproval.

ASTM B85 / B85M – 18e1 Standard Specification for Aluminum-Alloy Die Castings
It should be thoroughly understood that the data in Table X2. The purchaser shall have the right to perform any of the inspections and tests set forth in this speci?
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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. Rejection and Retest D Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range.
UNS designations were established in accordance with Practice E Unalloyed aluminum contains a minimum of Other methods may be used only when no published ASTM test method is available. Additions of small amounts of modifiers and grain refining elements or alloys are permitted. For this reason, it is considered that the only practical method for mechanical property control is proof testing the whole die casting.
The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard. All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works.
Prices subject to change without notice. G Based on resistance of alloy in standard type salt spray test.

Unless otherwise specified, only aluminum alloy conforming astk 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 derived SI unit for force is the newton Nwhich is de?
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Location of ejector pin marks or parting lines shall be at the option of the producer; unless speci? No one alloy is best in all categories. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. If, however, the presence of other elements is suspected, or indicated in the course of routine analysis, further analysis shall be made to determine that the total of these other elements are not present in excess of speci?
As much of the rejected original material as possible shall be returned to the producer or supplier. Thirteen of the most commonly die cast alloy compositions are speci? The location of the identi? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute.
Additions of small amounts of modi? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. B Die castings are not usually solution heat treated. Current edition approved April 10, It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
Ratings given for antisoldering are based on nominal iron compositions of approximately 1. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
Users of this standard are expressly advised xstm determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Characteristics of Die Casting Alloys Generally aluminum die castings are unsuitable for light color anodizing where asfm appearance is required. B For purposes of acceptance and rejection, the observed value or calculated value obtained from analysis should be rounded off to the nearest unit in the last right-hand place of?

All tests are performed in accordance with the appropriate ASTM test methods. J Ability of the alloy to take and hold an electroplate applied by present standard methods. The applicable levels shall be as speci? 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 abstract is a brief summary of the referenced standard. In case of dispute, the methods of analysis shall be agreed upon between the producer and the purchaser.
