Characteristics of Die Casting Alloys 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? Die castings inspected by this method shall be so adtm or handled during the? Sampling shall be in accordance with Practices E 88 or Eor both. Packaging and Package Marking Pure materials, recycled materials, and master alloys and material not conforming atsm 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.
This specification covers aluminum-alloy die castings of all compositions. Additions of small amounts of modifiers and grain refining elements or alloys are permitted. Prices subject to change without notice.
ASTM B85 / B85M – 18e1 Standard Specification for Aluminum-Alloy Die Castings
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. Except as otherwise speci?
Last previous edition approved in as B 85 — 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.
In considering these ratings, it should be noted that all the alloys have sufficiently good characteristics to be accepted by users and producers of v85 castings. All tests are performed in accordance with the appropriate ASTM test methods. Combining values from the two systems may b58 in non-conformance with the standard.
UNS designations were established aatm accordance with Practice E 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.
No one alloy is best in all categories. B58 Composite rating based on ease of cutting, chip characteristics, quality of? The producer or supplier may use a system of statistical quality control for such examinations. C Limits are in percent maximum unless shown otherwise. The b885 shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints or drawings.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. A rating of 1 gives the best performance, 5 the poorest performance. A designation not in con?
D Ability of alloy to withstand stresses from contraction while cooling through hot-short or brittle temperature range.
ASTM B85 Grade SC84B
Current edition approved April 10, This specification covers aluminum-alloy die castings of all compositions. This abstract is a brief n85 of the referenced standard. Location of ejector pin marks or parting lines shall be at the option of the producer; unless speci? G Based on resistance of alloy b885 standard type salt spray test. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Your comments are invited either zstm revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The applicable levels shall be as speci? 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. K Rated on lightness of color, brightness and uniformity of clear anodized coating applied in sulphuric acid electrolyte.
All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works. Generally aluminum die castings are unsuitable for light color anodizing where pleasing appearance is required. Moore Specimen, cycles, ksi MPa 20 18 20 20 Ratings given for antisoldering are based on bb85 iron compositions of approximately 1.
Additions of small amounts of modifiers and grain refining elements or alloys are permitted. 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.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. The marking shall consist of raised Arabic numerals, and when applicable capital letters, cast integral. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
J Ability of the alloy to take and hold an electroplate applied by present standard methods.
Unless otherwise specified, only aluminum alloy xstm 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.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
