Al is the base.
According to GOST 295-98, the total mass fraction of aluminum and magnesium should be ≥ 91.0%. The total mass fraction of impurities (indicated in the table + iron, manganese and nickel) ≤ 9.0%. At the consumer's request, the mass fraction of tin in aluminum may not be more than 0.030%, in this case the mark has the designation AB91F.
