TECHNICAL REQUIREMENTS 3
11、.1 Composition Shall conform to the percentages by weight shown in Table 1, determined by wet chemical methods in accordance with ASTM E 478, by spectrochemical methods, or by other analytical methods acceptable to purchaser. TABLE 1 - COMPOSITION Element (3.1.1) min max Copper 68.5 71.5 Lead - 0.07
12、 Iron - 0.05 Zinc (3.1.2) remainder - Sum of Named Elements (3.1.1) 99.7 - 3.1.1 These composition limits do not preclude the presence of other elements. Limits may be established and analysis required for unnamed elements by agreement between the manufacturer or supplier and purchaser. 3.1.2 Zinc m
13、ay be reported as “remainder”, or as the difference between the sum of results for all elements and 100%, or as the result of direct analysis. 3.1.3 When all the elements in the table are analyzed, the sum shall be 99.7% minimum, but such determination is not required for routine acceptance of each
14、lot. 3.2 Condition Cold rolled and fully recrystallized, annealed (OS035) temper (See 8.2). 3.3 Properties The product shall conform to the following requirements: 3.3.1 Average Grain Size Shall be 0.025 to 0.050 mm, determined in accordance with ASTM E 112. 3.3.2 Hardness Shall be 25 to 38 HR30TW,
15、or equivalent, determined in accordance with ASTM E 18. 3.4 Quality The product, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to usage of the product. SAE INTERNATIONAL AMS4505K Page 3 of 4 3.5 Toleranc
16、es Shall conform to AMS2222 as applicable to nonrefractory alloys. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of the product shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right t
17、o sample and to perform any confirmatory testing deemed necessary to ensure that the product conforms to specified requirements. 4.2 Classification of Tests All technical requirements are acceptance tests and shall be performed on each lot. 4.3 Sampling and Testing Shall be in accordance with ASTM B
18、 248 or ASTM B 248M. 4.4 Reports The vendor of the product shall furnish with each shipment a report showing the results of tests on each lot to determine conformance to all technical requirements. This report shall include the purchase order number, lot number, AMS4505K, size, and quantity. 4.5 Res
19、ampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, disposition of the product may be based on the results of testing two additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified requiremen
20、ts shall be cause for rejection of the product represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Identification The product shall be identified as in 5.1.1 unless line marking as in 5.1.2 is specified by purchaser. 5.1.1 Each sheet, strip, and plate shall be legibl
21、y marked near one end, coils being marked near the outside end, with AMS4505K, lot number, manufacturers identification, and nominal thickness, using any suitable marking fluid.

The markings shall have no deleterious effect on the product or its performance and shall be sufficiently stable to withstand normal handling. The specification number, manufacturers ide
24、ntification, and nominal thickness shall be continuously line marked; the lot number may be included in the line marking or may be marked at one location on each piece. 5.1.2.1 Flat Strip 6 Inches (152 mm) and Under in Width Shall be marked in one or more lengthwise rows of characters recurring at i
25、ntervals not greater than 3 feet (914 mm). SAE INTERNATIONAL AMS4505K Page 4 of 4 5.1.2.2 Flat Sheet, Flat Strip Over 6 Inches (152 mm) in Width, and Plate Shall be marked in lengthwise rows of characters recurring at intervals not greater than 3 feet (914 mm), the rows being spaced not more than 6
