ASTM B85 – 96 Standard Specification for Aluminum-Alloy Die Castings
Quality assurance standards shall be agreed upon between the producer or supplier and purchaser at the time a contract or order is placed. 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 axtm 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.
Unless otherwise n85, 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. 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.
Die castings are not generally 8b5 or arc welded or brazed.

The derived SI unit for force is the newton Nwhich is de? This specification covers aluminum-alloy die castings of all compositions. The following bibliographic material is provided to assist you with your purchasing decision: L Rated on combined resistance of coating and base alloy to corrosion.
In considering these ratings, it should be noted that all the alloys have sufficiently good characteristics to be accepted by users and producers of die castings. E Ability of molten alloy to? Hence the rating for each characteristic is a relative measure of that attribute compared to the same attribute in another alloy. Dimensions, Mass, and Permissible Variations Sampling shall be in accordance with Practices E 88 wstm Eor both.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of aatm other. Your comments are invited either b885 revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Ratings given for antisoldering are based on nominal iron compositions of approximately 1. Unalloyed aluminum contains a minimum of The producer or supplier may use a system of statistical quality control for such examinations. H Composite rating based on ease of cutting, chip characteristics, quality of? The marking shall consist of raised Arabic numerals, and when applicable capital letters, cast integral. This specification covers aluminum-alloy die castings of all compositions.

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? A number in parentheses indicates the year of last reapproval. Each package shall contain only one type of item unless b8 agreed upon.
Conformance shall be determined by the producer by analyzing samples taken at the time castings are made. B Die castings are not usually solution heat treated. Low temperature aging treatments may be used for stress relief or dimensional stability. 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?
