Deoxidation: Aluminum Rod 12 is utilized in the steel industry for deoxidation purposes. Deoxidation is a critical step in the steelmaking process aimed at removing oxygen from the molten steel. The presence of oxygen in steel can significantly alter its mechanical properties, rendering it brittle and less flexible. Aluminum serves as one of the most common deoxidizers for steel. With its high affinity for oxygen, aluminum effectively reacts with the oxygen present in the molten steel, forming aluminum oxide (Al2O3). While this aluminum oxide remains as an impurity in the steel, it does not have detrimental effects akin to free oxygen.
