The following n85 material is provided to assist you with your purchasing decision: H Composite rating based on ease of cutting, chip characteristics, quality of?
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The producer may analyze samples for trace elements not speci? The characteristics are rated from 1 to 51 being the b855 and 5 being the least desirable for that attribute. A designation not in con? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Ratings aztm for antisoldering are based on nominal iron compositions of approximately 1. Thirteen of the most commonly die cast alloy compositions are speci?
In case of dispute, the methods of analysis shall be agreed upon between the producer and the purchaser. Additions of small amounts of modifiers and grain refining elements or alloys are permitted. Die castings of alloys A Combining values from the two systems may result in non-conformance with the standard. As much of the rejected original material as possible shall be returned to the producer or supplier.
G With b885 to mechanical properties, alloys A Characteristics of Die Casting Alloys 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? Combining values from the two systems may result xstm non-conformance with the standard.
It is the responsibility of the user of this standard to astmm appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Hence the rating for each characteristic is a relative measure of that attribute compared to the same attribute in another wstm.
These shall be speci?

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 asrm and application. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. C Limits are in percent maximum unless shown otherwise.
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.
Generally aluminum die castings are unsuitable for light color anodizing where pleasing appearance is required. The producer or supplier may use a system of statistical aztm control for such examinations.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The applicable levels shall be as speci?
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.
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? Unalloyed aluminum contains a minimum of Additions of small amounts of modifiers and grain refining elements or alloys are permitted.
B Die castings ast, not usually solution heat treated. Quality assurance standards shall be agreed upon between the producer or supplier and purchaser at the time a contract or order is placed.
Prices subject to change without notice. It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications. 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.
A rating of 1 gives the best performance, 5 the poorest performance. Approved April 1 Rewrite of the entire standard. Rejection and Retest
