Iron

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.

Where is Iron used?

• Mining and metals: direct feedstock
• Sintered components, powder metallurgy parts, and metal injection molding for automotive and industrial machinery
• Pharmaceuticals: active ingredient in iron-fortification tablets and nutritional supplements
• Coatings: reactive component in anti-corrosion primers
• In chemical synthesis, elemental iron functions as a heterogeneous catalyst and reducing agent in batch reactions, including aniline production.

Good to know: Controlled particle size determines bioavailability and dosing consistency in supplements. Grades include USP/FCC for food and pharmaceutical use, carbonyl iron for high-purity applications, and reduced iron for industrial processes.

Commercial specifications

• Particle size specifications are critical for powder metallurgy and pharmaceutical applications
