Low temperature aging treatments may be used for stress relief or dimensional stability. Link to Active This link will always route to the current Active version of the standard. All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works.
F Ability of molten alloy to? 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.
ASTM B85 – 96 Standard Specification for Aluminum-Alloy Die Castings
When the location is not speci? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Die castings of alloys A Different machines and dies continue to be necessary for die castings and test bars. L Rated on combined resistance of coating and base alloy to corrosion. Current edition approved April 10, Packaging and Package Marking G Based on resistance of alloy in standard type salt spray test.
Die castings are not generally gas or arc welded or brazed. In case of dispute, the methods of analysis shall be agreed upon between the producer and the purchaser. B For purposes of acceptance and rejection, the observed value or calculated satm obtained from analysis should be rounded off to the nearest unit in the last right-hand place of? Except as otherwise speci? Additions of small amounts of modifiers and xstm refining elements or alloys are permitted.
This specification covers aluminum-alloy die castings of all compositions. Combining values from the two systems may result in non-conformance with the standard. The standards or requirements may consist of radiographs in accordance with Reference Radiographs Ephotographs or sectioned die castings.
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. It is informational only and not an official part of the standard; the full text of the standard itself must be referred qstm for its use and application.
This standard has been approved for use by agencies of the Department of Defense. Die castings inspected by this method shall be so marked or handled during the? It may not address the mechanical properties, integrity testing, and verification required for highly loaded or safety critical applications. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
However, ratings of 5 may present manufacturing difficulties. The purchaser shall have the right to perform any of the inspections and tests set forth in this speci?
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Additions of small amounts of modi?
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.
H Composite rating based on ease of cutting, chip characteristics, quality of? Marking for shipment shall be in accordance with Fed. No one alloy is best in all categories. For this reason, it is considered that the only practical method for mechanical property control is proof testing the whole die casting. Moore Specimen, cycles, ksi MPa 20 18 20 20 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.
The castings shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints or drawings.
When tension or impact tests are made, the tension test specimen shown in Fig.
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? B Die castings are not usually solution heat treated.

V85 the rating for each characteristic is a relative measure of that attribute compared to the same attribute in another alloy. Each package shall contain only one type of item unless otherwise agreed upon.
Unalloyed aluminum contains a minimum of
