4. Process
4.1 The alloys may be made by any approved process.
5. Quality
5.1 The material covered by this specification shall be of uniform quality and shall be free from dross, slag, and other harmful contamination.
6. Chemical Composition
6. 1 The ingots or molten metal shall conform to the chemical composition limits prescribed in Table 1. Conformance shall be determined by the producer by taking samples at the time the ingots are poured into molds or as the molten alloy is poured into the crucible(s)prior to shipment in accordance with Practice E716 and analyzed in accordance with Test Methods E34. E607 or E1251. or EN 14242.
7. Electrical Conductivity
7.1 The control of chemical requirements in Table I ensures the capability of Alloys 100.1, 130.1, 150.1, and 170.1 to meet ited but not measured minimum conductivity in ingot form The rated minimum conductivities for rotor ingot (electric motor armatures ) and other high conductivity applications are listed in the footnote (*) of Table 1.
