Remelting aluminum ingots are divided into six grades based on chemical composition:
Al99.85, Al99.80, Al99.70, Al99.60, Al99.50, Al99.00.
The chemical composition of the remelted aluminum ingot should meet the stipulated number in the following table:
Al is not less than the chemical composition % impurity is not greater than Fe Si Cu Ga other each sum
Al99.85 99.85 0.12 0.08 0.005 0.030 0.030 0.015 0.15
Al99.80 99.80 0.15 0.10 0.01 0.03 0.03 0.02 0.20
Al99.70 99.70 0.20 0.13 0.01 0.03 0.03 0.03 0.30
Al99.60 99.60 0.25 0.18 0.01 0.03 0.03 0.03 0.40
