TECHNICAL REQUIREMENTS 3.1 Composition Shall conform to the percentages by weight shown in Table 1, determined by wet c
11、hemical methods in accordance with ASTM E478, by spectrochemical methods, or by other analytical methods acceptable to purchaser. Table 1 - Composition Element (3.1.1) min max Aluminum 8.5 10.0 Iron 2.0 4.0 Nickel (including Cobalt) - 1.0 Tin - 0.6 Manganese - 0.50 Silicon - 0.25 Copper (including S
12、ilver) (See 3.1.2) Sum of Named Elements (3.1.3) 99.5 - 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 Copper may be reported as
13、 “remainder”, or as the difference between the sum of results for all analyzed elements and 100%, or as the result of direct analysis. 3.1.3 When all named elements in Table 1 are analyzed, the sum shall be 99.5% minimum, but such determination is not required for routine acceptance of each lot. 3.2
14、 Condition The product shall be supplied in the following condition: 3.2.1 Bars and Rods As rolled or extruded and stress relieved. 3.2.2 Forgings Stress relieved. 3.2.3 Forging Stock As ordered by the forging manufacturer. 3.3 Properties The product shall conform to the following requirements: SAE
