Ferrous materials are metals that contain iron, making them magnetic and typically strong. Common examples include steel and cast iron, which are widely used in construction, manufacturing, and various industrial applications due to their durability and ability to withstand heavy loads. These materials can be further categorized into two main types: carbon steel, which contains varying amounts of carbon, and alloy steel, which includes other elements to enhance specific properties. Ferrous materials are essential in creating tools, machinery, and infrastructure, playing a crucial role in modern engineering and technology.
