Well, Ferrous metals, like steel and iron, have iron as their main part. They're magnetic and can rust easily. Non-ferrous metals, such as aluminum and copper, don't have iron. They aren't magnetic and don't rust easily. Separating them when recycling helps keep the materials good for making new things and saves resources. Furthermore, Ferrous metals are common in big industries, but non-ferrous metals, with their special traits, are also valuable in many areas, like electronics and construction.
