ASTM B197/B197M-20

Standard Specification for Copper-Beryllium Alloy Wire

ABSTRACT
This specification establishes the requirements for copper-beryllium alloy (Copper Alloy UNS Nos. C17200 and C173002) wires in coils, spools, or other forms except straight lengths, of any uniform cross section. Products shall be available in the following tempers: solution heat-treated TB00, and cold-worked TD00 to TD04, which shall be precipitation heat treated after forming. Products that are already precipitation heat treated by the manufacturer shall be available in tempers TF00 (AT), and TH01 to TH04. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (diameter, thickness, length, width, and straightness), mechanical (tensile and bend strength, Rockwell hardness, and elongation), physical (grain size and count), and chemical composition requirements.
SCOPE
1.1 This specification establishes the requirements for copper-beryllium alloy wire in coils, spools, or other than straight lengths, of any uniform cross section. Copper Alloy UNS Nos. C17200 and C173002 are included.  
1.2 Unless otherwise required, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B197/B197M is specified without any alloy designation.  
1.3 The values stated in either inch-pounds units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 The following safety hazard caveat pertains only to the test methods described in this specification:  
1.4.1 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.  
1.5 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.

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.
