Which metal contains iron, is usually magnetic and prone to corrosion unless protected?

Explanation:
Metals that contain iron are ferrous metals. Iron gives these metals magnetic properties, so they’re usually magnetic. They’re also prone to corrosion (rust) when exposed to moisture and oxygen unless protected by coatings, galvanizing, or alloying (as with steel or stainless steel). In contrast, non-ferrous metals do not contain iron, so they’re not typically magnetic and have different corrosion behavior, thermoplastics are plastics, and sustainability is a concept, not a metal. Therefore, the description points to ferrous metal.
