The main difference between pure iron and electrical pure iron in terms of composition lies in the aluminum content and the content of other impurity elements.
Difference in composition
Aluminum content:
Pure iron: The aluminum content is less than 0.2%. The iron content of pure iron can reach 99.9%, but its aluminum content is lower. Electrical pure iron: The aluminum content is as high as 65%. The higher the aluminum content of electrical pure iron, the better, because aluminum has better conductivity and ductility than iron. Other impurity elements:
Pure iron: Its composition includes carbon (C) ≤0.008%, phosphorus (P) ≤0.10%, sulfur (S) ≤0.10%, manganese (Mn) ≤0.1%, silicon (Si) ≤0.01%, copper (Cu) ≤0.01%.
Electrical pure iron: Its composition includes iron (Fe) content of 99.50%-99.90%, carbon (C) ≤0.04%, and the content of impurity elements such as phosphorus (P), sulfur (S), and manganese (Mn) is as low as possible.
