Iron powder is widely used in the manufacturing of powdered metal parts, especially in the automotive and machinery industries, where it serves as a cost-effective raw material for producing gears, bearings, and structural components through compression and sintering. It is also a key ingredient in the production of magnets and electromagnetic cores due to its magnetic properties. In chemical applications, iron powder acts as a reducing agent in organic synthesis and in the removal of contaminants from wastewater through reductive precipitation. It is used in the thermite reaction for welding and metal cutting. Additionally, iron powder is employed in nutritional supplements and food fortification as a source of dietary iron, and in hand warmers where it undergoes oxidation to generate heat.
