In contrast with other components (similar to calcium, aluminum, silicon), the power of deoxidization of manganese within the molten metal is low, however due to its simple to manufacturing, the worth is low, so still deeply iron and steel enterprise's welcome, particularly for refined rimming steel speaking, using ferromanganese alloy deoxidizing is right deoxidizer, for manganese of deoxidizing capability is weak, it may possibly alter the metal oxygen content, and unapt make oxygen off too much and not boiling. galvanized steel pipe

In 1808, Sir Humphry Davy identified the existence of the metallic in alum, which he at first named "alumium" and later "aluminum."
