The Iron Triad is composed of three elements: iron (Fe), cobalt (Co), and nickel (Ni), which share similar chemical and physical characteristics. If iron does rust, this is a slow chemical change since rust is an iron oxide with different properties than iron metal. Owing to the structure of this metal, it exhibits numerous magnetic properties. Softness – one of the most well known mechanical properties of iron is its level of hardness. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Other physical properties, such as the melting temperature of iron or the freezing temperature of water, can only be observed as matter undergoes a physical change. It is known to exist in four distinct crystalline forms. Iron may cause conjunctivitis, choroiditis, and retinitis if it contacts and remains in the tissues.
