Overview

Iron (CAS 7439-89-6) is a metallic chemical element with high structural strength and magnetic properties, essential for industrial manufacturing processes. Iron represents one of the most fundamental and widely utilized metals in industrial applications worldwide. As a pure metallic element with the chemical symbol Fe, iron exhibits exceptional mechanical properties that make it indispensable across numerous sectors. This transition metal demonstrates remarkable versatility, serving as both a standalone material and a critical component in alloy formation. The metal's inherent properties include excellent electrical conductivity, substantial tensile strength, and distinctive ferromagnetic characteristics. Iron's ability to form various oxidation states enables diverse chemical reactions and applications. While classified under ADR Class 4.2 due to its potential for spontaneous combustion in finely divided forms, metallic iron in bulk form presents minimal safety concerns under normal handling conditions. Iron finds extensive application in steel production, where it serves as the primary constituent in creating high-strength structural materials for construction and automotive industries. The electronics sector utilizes iron in electromagnetic components, transformers, and magnetic core applications. Additionally, iron plays a crucial role in chemical synthesis processes as a catalyst or reducing agent. Unlike organometallic compounds such as tris(2-methylpropyl)alumane or tripropylalumane, which serve specialized catalytic functions, iron offers broader industrial utility due to its fundamental metallic nature and cost-effectiveness. Its compatibility with various processing methods, from casting to powder metallurgy, enhances its appeal for manufacturers seeking reliable material solutions. OYSI maintains comprehensive iron supplies to support European industrial requirements, ensuring consistent quality and reliable delivery for technical applications.

Frequently Asked Questions

What is iron?

Iron is a metallic chemical element with the symbol Fe (from Latin ferrum) and atomic number 26. It is the fourth most abundant element in Earth's crust and one of the most important metals in human civilization. Iron has a molecular weight of 55.84 g/mol and exists primarily as a silvery-gray metal in its pure form. It is essential for steel production and various industrial applications due to its strength, magnetic properties, and abundance.

What are the physicochemical properties of iron?

Iron is a lustrous, silvery-gray metal that is solid at room temperature with a melting point of 1,538°C. It exhibits ferromagnetic properties and is relatively dense with a specific gravity of 7.87. Pure iron is relatively soft but becomes harder when alloyed with carbon and other elements. It is insoluble in water but readily oxidizes in moist air, forming rust. Iron has good thermal and electrical conductivity and can exist in multiple oxidation states.

What is iron used for?

Iron serves as the primary raw material for steel production, which is essential for construction, automotive, and manufacturing industries. It is used in the production of cast iron products, machinery components, and tools. In the chemical industry, iron compounds serve as catalysts, pigments, and water treatment agents. Iron is also utilized in powder metallurgy, magnetic applications, and as a nutritional supplement in the food and pharmaceutical industries.

How to handle iron safely?

Iron powder requires careful handling due to its potential fire hazard when finely divided. Wear appropriate personal protective equipment including safety glasses, dust masks, and protective clothing to prevent inhalation and skin contact. Ensure adequate ventilation to minimize dust exposure. Avoid generating dust clouds and keep away from ignition sources. Use grounding and bonding procedures when transferring iron powder. Regular housekeeping prevents dust accumulation that could create fire or explosion risks.

How to store iron correctly?

Iron should be stored in a dry, well-ventilated area away from moisture to prevent oxidation and rust formation. Keep containers tightly closed and protect from humidity using appropriate packaging or desiccants. Store iron powder away from oxidizing agents, acids, and incompatible materials. Maintain storage areas below 30°C and ensure adequate fire protection measures are in place. Regular inspection of storage conditions helps prevent deterioration and maintains product quality.

What to do in case of contact with iron?

Iron contact typically presents minimal immediate health risks for solid forms. If iron dust contacts eyes, flush immediately with clean water for at least 15 minutes and seek medical attention if irritation persists. For skin contact, wash thoroughly with soap and water. If iron dust is inhaled, move to fresh air immediately. In case of ingestion of iron compounds, do not induce vomiting and seek medical attention. Remove contaminated clothing if necessary.

How to dispose of iron appropriately?

Iron can be recycled through metal recovery programs, making it an environmentally sustainable material. Contact licensed waste management companies for collection and processing of iron waste. Clean iron scrap can typically be sold to scrap metal dealers. Contaminated iron may require special handling depending on the type of contamination. Follow local waste regulations and avoid disposing of iron in regular municipal waste streams to maximize recycling opportunities.

How to transport iron?

Iron powder is classified under ADR Class 4.2 (substances liable to spontaneous combustion) Packing Group III, requiring specific transport precautions. Use appropriate packaging that prevents moisture ingress and provides adequate ventilation. Transport vehicles must comply with ADR regulations including proper labeling, documentation, and emergency equipment. Solid iron forms typically have fewer transport restrictions but still require proper securing to prevent shifting during transport and appropriate documentation.

Is iron subject to particular regulations?

Iron is regulated under REACH as a registered substance but is not classified as a Substance of Very High Concern (SVHC). It does not require CLP hazard classification in its metallic form. However, iron powder may be subject to additional safety regulations due to its potential fire hazard. Industrial users must comply with workplace safety regulations and proper handling procedures. Environmental regulations may apply to iron-containing waste streams and emissions.
