ASTM B592-20

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: B592 − 15 B592 − 20
Standard Specification for
Copper-Zinc-Aluminum-Cobalt Alloy, Copper-Zinc-Tin-Iron
Alloy Plate, Sheet, Strip, and Rolled Bar
This standard is issued under the fixed designation B592; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This specification establishes the requirements for Copper Alloy UNS C66300 and C68800 plate, sheet, strip, and rolled
bar.
NOTE 1—Since alloy C68800 is frequently used in a variety of applications where yield strength and stress-corrosion resistance may be critical, it is
recommended that drawings or samples of the part to be fabricated and details of application be submitted for use in establishing temper and treatment
of material.
NOTE 2—Alloy C66300 is covered by a patent. Interested parties are invited to submit information regarding the identification of an alternative(s) to
this patented item to the ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical
committee, which you may attend.
1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are
mathematical conversions to SI units, which are provided for information only and are not considered standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

6. Materials and Manufacture
6.1 Materials:
6.1.1 The material of manufacture shall be a form (cast bar, cake, slab, et cetera) etc.) of Copper Alloy UNS No. C66300 or
C68800 of such purity and soundness as to be suitable for processing into the products prescribed herein.
6.1.2 When specified in the contract or purchase order that heat identification or traceability is required, the purchaser shall
specify the details desired.
NOTE 2—Due to the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify a specific casting
analysis with a specific quantity of finished material.
6.2 Manufacture:
6.2.1 The product shall be manufactured by such hot working, cold working, and annealing processes as to produce a uniform
wrought structure in the finished product.
6.2.2 The product shall be hot-hot or cold-worked cold worked to the finished size, and subsequently annealed,annealed when
required, to meet the temper properties specified.
B592 − 20

7.2 These composition limits do not preclude the presence of other elements. By arrangementagreement between the
manufacturer and purchaser, limits may be established and analysis required for unnamed elements.
7.3 For alloys in which copper is listed as “remainder,” copper is the difference between the sum of results of all elements
determined and 100 %. When all elements in Table 1 are determined, the sum of the results shall equal at least 99.5 %.be 99.5 %
min.
