This method specifies the method for the determination of aluminum content in copper and copper alloys. This section applies to the determination of aluminum content in copper and copper alloys. Method 1 Measuring range: 0.0010% to 0.50%. Method 2 Determination range: >0.50%~12.00%. Method 3 specifies the determination of aluminum in copper alloys by the volumetric method. Method 3 is applicable to the determination of aluminum as an element in all types of copper alloys in ISO recommended standards.
