注：
1. The content of Al is the calculated difference between 100% and the sum of the impurities as Fe, Si, Cu, Zn and Ti.
2. Other impurities that not list in the table, the buyer and the seller can negotiate if needed.
3. We use rounding comparison method for the determination of value analysis. According to the rules of GB/T8170, rounding digital should be the same as limit digital list in the table.
