Overview
Iron (CAS 7439-89-6 ), commonly designated Fe, is the elemental metal that underpins modern industrial manufacturing across metallurgy, chemical synthesis, and advanced materials production.
As a base metal and catalyst precursor, it drives processes ranging from large-scale chemical reactions to precision powder metallurgy. In the mining and metals sector, iron powder is a direct feedstock.
It is used for sintered components, powder metallurgy parts, and metal injection molding used in automotive and industrial machinery. Pharmaceutical manufacturers use high-purity iron powder as an active ingredient.
This is utilized in iron-fortification tablets and nutritional supplements, where controlled particle size determines bioavailability and dosing consistency. Coatings formulators incorporate iron-based materials as precursors.
These are used as reactive components in anti-corrosion primers, where the metal's reactivity drives protective film formation. In chemical synthesis, elemental iron functions as a heterogeneous catalyst.
It acts as a reducing agent in batch reactions, including the production of aniline and other industrial intermediates. Iron is supplied in multiple physical forms including powder, granules, sponge, and ingot.
Particle size specifications are critical for powder metallurgy and pharmaceutical applications. Recognized grades include USP / FCC for food and pharmaceutical use and carbonyl iron for high-purity applications.
Reduced iron is also available for industrial processes. Technical-grade material is available in bulk quantities for mining, coatings, and catalyst manufacturing across various global industrial sectors.
