- Scope
- This part specifies the determination method for the manganese content in high manganese aluminum bronze ZCuA18Mn14Fe3Ni2, ZCuA18Mn12Fe3Ni2 and ZCuA18Mn13Fe3Ni2 materials for propellers using the trivalent manganese-ferrous ammonium sulfate titration method and the heptavalent manganese ferrous ammonium sulfate titration method. This section is applicable to the determination of the manganese content in the high manganese aluminum bronze ZCuA18Mn14Fe3Ni2, ZCuA18Mn12Fe3Ni2 and ZCuA18Mn13Fe3Ni2 materials for propellers in the range of 8.00%~17.00%.
