ASTM B747-20

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: B747 − 15 B747 − 20
Standard Specification for
1
Copper-Zirconium Alloy Sheet and Strip
This standard is issued under the fixed designation B747; 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 C15100 sheet and strip.
1.2 Units—Values The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are
mathematical conversions to SI units, whichunits that are provided for information only and are not considered standard.
1.2.1 Exception—Values given in inch-pound units are the standard except for grain size, which is stated in SI units.
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.
