Characteristics of Die Casting Alloys The producer may analyze samples for trace elements not speci? Each package shall contain only one type of item unless otherwise agreed upon.
Except as otherwise speci? E Ability of molten alloy to?
L Rated on combined resistance of coating awtm base alloy to corrosion. The applicable levels shall be as speci? Generally aluminum die castings are unsuitable for light color anodizing where pleasing appearance is required. The values stated in each system may not be exact equivalents; ast, each system shall be used independently of the other. A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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 use.
I Composite rating based on ease and speed of polishing and quality of? 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. 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.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Additions of small aetm of modifiers and grain refining elements or alloys are permitted. Marking for shipment shall be in accordance with Fed.
The location of the identi? If the producer has determined the chemical composition of the metal during the course of manufacture, he shall not be required to sample and analyze the?
Prices subject to change without notice. ASTM International takes no position respecting the validity of any patent rights asserted in connection b855 any item mentioned in this standard. The producer or supplier may use a system of statistical quality control for such examinations.
This abstract is a brief summary of the referenced standard. Historical Version b885 – view previous versions of standard. Hence the rating for each characteristic is a relative measure of that attribute compared to the same attribute in another alloy.
G Based on resistance of alloy in standard type salt spray test. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk 8b5 infringement of such rights, are entirely their own responsibility. J Ability of the alloy to take and hold an electroplate applied by present standard methods. The following bibliographic material is provided to assist you with your purchasing decision: Other methods may be used only when no published ASTM test method is available.
When tension or impact tests are made, the tension test specimen shown in Fig. 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.
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? It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications.
Quality assurance standards shall be agreed upon between the producer or supplier and purchaser at the time a contract or order is placed. The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute. 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.
A rating of 1 gives the best performance, 5 the poorest performance. Different machines and dies continue to be necessary for die castings and test bars. Originally approved in Thirteen of the most commonly die cast alloy compositions are speci? B Die castings are not usually solution heat treated. 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.
All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works. A designation not in con? Link to Active This link will always route to the current Active version of the standard.
