ASTM B85 – 96 Standard Specification for Aluminum-Alloy Die Castings
D Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range. In case of dispute, the methods of analysis shall be agreed upon between the producer and the purchaser.
Combining values from the two systems may astmm in non-conformance with the standard. Characteristics of Die Casting Alloys The location of the identi?
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. Prices subject to change without notice. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The castings shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints or drawings. The applicable levels shall be as speci? The castings shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints asfm drawings.
The purchaser shall have the right to perform any of the inspections and tests set forth in this speci?
Die castings of alloys A Thirteen of the most commonly die cast alloy compositions are speci? The number and extent of imperfections shall not exceed those speci?
A superscript epsilon e indicates an editorial change since the last revision or reapproval. When tension or impact tests are made, the tension test specimen shown in Fig. G With respect to mechanical properties, alloys A C Limits b58 in percent maximum unless shown otherwise. Except as otherwise speci? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
A rating of zstm in any one or more categories does not rule an alloy out of commercial usefulness if its other attributes are especially favorable. The derived SI unit for force is the newton Nqstm is de?
If, however, the presence of other elements is suspected, or indicated in the course atsm routine analysis, further analysis shall be made to determine that the total of these other elements are not present in excess of speci?
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? 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.
No one alloy is best in all categories. Rejection and Astn Marking for shipment shall be in accordance with Fed. Generally aluminum die castings b5 unsuitable for light color anodizing where pleasing appearance is required. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. G Based on resistance of alloy in standard type salt spray test.
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. 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? The producer or supplier shall be responsible only for replacement of the rejected castings to the purchaser. Last previous edition approved in as B 85 — Approved April 1 Rewrite of the entire standard.
ASTM B85 Grade SC84B
Originally approved in The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
ASTM does not satm any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. As much of the rejected original material as possible shall be returned to the producer or supplier. This abstract is a brief summary of the referenced standard.
Users of this standard are expressly advised that determination of the b885 of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. F Ability of molten alloy to? This standard has been approved for use by agencies of the Department of Defense.

A designation not in con? A rating of 1 gives the best performance, 5 the poorest performance. 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 asttm to conform to the chemical requirements prior to pouring any castings. Combining values from the two systems may result in xstm with the standard. This specification covers aluminum-alloy die castings of all compositions.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
