What is the primary disadvantage of ferrous metals?

The primary disadvantage of ferrous metals is their high susceptibility to corrosion. Ferrous metals, which include steel and iron-based alloys, contain iron as a major component. When exposed to moisture and oxygen, they undergo a chemical reaction that leads to rust formation, compromising their structural integrity over time. This corrosion can reduce the lifespan of components made from ferrous metals and necessitate additional maintenance or protective coatings to mitigate the effects.

While other characteristics such as low melting points or high density might be relevant to specific applications, they do not represent a primary drawback of ferrous metals. Additionally, ferrous metals generally exhibit good weldability, particularly when appropriate techniques and equipment are used. Thus, the high susceptibility to corrosion stands out as a significant concern when working with these materials, making protective measures essential in environments prone to moisture or corrosive agents.
