Iron powder is widely used in the manufacturing of powdered metal parts, especially in the automotive and machinery industries, where it serves as a base material for sintered components like gears, bearings, and bushings due to its compressibility and bonding properties. It is also a key ingredient in the production of magnetic cores for electrical and electronic devices, benefiting from its magnetic permeability and low electrical conductivity when insulated. In the chemical industry, iron powder acts as a reducing agent in organic synthesis and in the removal of impurities from industrial waste streams. It is used in thermite mixtures for welding and cutting metals in field operations. Additionally, iron powder is incorporated into food packaging as an oxygen scavenger to extend shelf life by preventing oxidation. In agriculture and environmental applications, it helps in soil remediation and nutrient delivery due to its reactivity and ability to release iron ions gradually. It is also used in self-heating products like hand warmers, where oxidation with atmospheric oxygen generates heat.
