Materials and Manufacture 6.1 Material: 6.1.1 The material of manufacture shall be Copper Alloy UNS No. C17000, C17200, or C17300, cast and worked and of such purity and soundness as to be suitable for processing into the products prescribed herein. 6.1.2 Heat traceability shall be maintained and reported on the Mill Test Report or Certification. 6.2 Manufacture: 6.2.1 The product shall be produced with a combination hot working, cold working, and thermal processing to produce a uniform wrought structure and the specified temper. 7. Chemical Composition 7.1 The material shall conform to the chemical composition requirements prescribed in Table 1 for Copper Alloy UNS No. designation specified in the ordering information. 7.2 These composition limits do not preclude the presence of other elements. Limits for unnamed elements may be established and analysis required by agreement between the manufacturer, or supplier, and purchaser. 7.3 Copper is customarily given as remainder, but may be taken as the difference between the sum of all elements analyzed and 100 %. 7.4 When all the elements in Table 1 are determined, the sum of results shall be 99.5 % min. 8. Temper 8.1 The standard temper designations available under this specification and as specified in Practice B 601 are solution heat-treated TB00 (A), and cold-drawn hard TD04 (H), (see Table 2) to be precipitation heat treated by the user. Also available are products already precipitation heat treated by the manufacturer, tempers TF00 (AT) and TH04 (HT). These products meet property requirements in Table 3 and normally require no further heat treatment by the user. 9. Precipitation Heat Treatment 9.1 The precipitation heat treatment is performed on TB00 (A) and TD04 (H) tempers by the purchaser, after machining or forming. 9.2 Conformance to the TF00 (AT) and TH04 (HT) speci- fication limits shown in Table 3, for products supplied in the TB00 (A) or the TD04 (H) tempers, shall be determined by testing test specimens heat treated at a uniform temperature of 600 to 675°F (316 to 357°C) for the times shown in Table 4. 9.3 End products may be heat treated at other times and temperatures for specific applications. These special combina- tions of properties such as increased ductility, electrical con- ductivity, dimensional accuracy, endurance life, and resistance to elastic drift and hysteresis in springs, may be obtained by special precipitation-hardening heat treatments. The mechani- cal requirements of Table 3 do not apply to such special heat treatments. Specific test requirements as needed shall be agreed upon between the manufacturer or supplier and purchaser of the end product. 9.4 TF00 (AT) and TH04 (HT) tempers as standard mill- hardened products have been precipitation heat treated and tested by the manufacturer for conformance to the specification limits shown in Table 3. Further thermal treatments of these tempers are not normally required. 10. Mechanical Property Requirements 10.1 Tensile Test Requirements: 10.1.1 The tension test, in accordance with Test Methods E 8 or 8M, shall be the standard test for rod (round, hexagonal, and octagonal) and bar (square) having a nominal diameter or distance between parallel surfaces up to 3⁄8 in. [10 mm] incl, and other shapes having a nominal cross-sectional area up to 0.141 in.2 [100 mm2], incl. The tensile strength requirements shall be prescribed in Table 2 and Table 3 after precipitation heat treatment in accordance with 8.1. 10.2 Rockwell Hardness Requirements: 10.2.1 Hardness shall be the standard test for round, hex- agonal, octagonal, and square rod larger than 3⁄8 in.

(Approved April 1, 2007.) (1) Corrected the metric values in Section 10, Table 2, and Table 3 and changed the chemistry in Table 1 to correspond to the CDA chemistry. (2) In 4.2.1 the definition for grain count was eliminated as it does not appear in the standard. (3) Definitions for Heat and Lot in Section 14 were moved to Section 4, but no change was made to definitions. (4) Section 18 was a redundant portion of Section 3 and was removed. The following section was renumbered. (5) In Table 2 there was an overlap in the metric equivalent values 10 to 26 (incl.) and over 25 to 75 mm. This was corrected to the proper 10 – 25 incl. and over 25 to 75.
