1. Scope
1.1 This specification establishes the requirements for copper-beryllium alloy rod and bar in straight lengths. The following three alloys are included:
| Copper Alloy | Previously Used | Nominal Beryllium |
| UNS No. | Designations | Content, % |
| C17000 | Alloy 165 | 1.7 |
| C17200 | Alloy 25 | 1.9 |
| C17300 | | 1.9 |
| | +0.4 lead |
1.2 Unless otherwise required, Copper Alloy UNS No. C17200 shall be the alloy furnished whenever Specification B 196/B 196M is specified without any alloy designation.
1.3 The values stated in either inch-pounds or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
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 and health practices and determine the applicability of regulatory limitations prior to use.
