Standard Specification for Copper-Cobalt-Beryllium Alloy and Copper-Nickel-Beryllium Alloy Plate, Sheet, Strip, and Rolled Bar
The following bibliographic material is provided to assist you with your purchasing decision:
This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-cobalt-beryllium and copper-nickel-beryllium alloys with Copper Alloy UNS Nos. C17500 and C17510. The material for manufacture shall be cast and worked to such purity and soundness as to be suitable for processing by hot working, cold working, and thermal treatment to produce a uniform wrought structure and the specified temper. Products shall be produced in tempers TB00 (solution heat treated), or TD02 and TD04 (cold worked), TF00 or TH02 and TH04 (precipitation heat treated), or TM02 and TM04 (mill hardened). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, width, length, straightness, and edges), mechanical (tensile strength, Rockwell hardness, and elongation), electrical conductivity, and chemical composition requirements.
Scope
1.1 This specification establishes the requirements for plate, sheet, strip, and rolled bar. The following alloys are included:
| Previously | Nominal Composition, % | ||||
| Copper Alloy | Used | ||||
| UNS No. | Designation | Beryllium | Cobalt | Nickel | Iron |
| C17500 C17510 | Alloy 10 Alloy 3 or 14 | 0.6 0.4 | 2.5 ... | ... 1.8 | ... ... |
| C71700 | ... | 0.5 | ... | 31.0 | 0.70 |
1.2 The intent is to provide a system of interchangeable alloys.
1.3 Units—Values stated in inch-pound units are to be regarded standard. The values given in brackets are mathematical conversions to SI units, which are provided for information only.
1.4 The following safety hazard caveat pertains only to the test methods described in this specification:
1.5 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.
