Composition Notes:
The aluminum content for unalloyed aluminum made by a refining process is the difference between 100.00 percent and the sum of all other metallic elements present in amounts of 0.0010 percent of more each, expressed to the third decimal before determining the sum, which is rounded to the second decimal before subtracting. When an element's specified maximum limit is 0.0XX, an observed value or a calculated value greater than 0.0005 but less than 0.0010% is rounded off and shown as " less than 0.001 ".
