What advantage do non-ferrous metals typically have over ferrous metals?

Non-ferrous metals are known for their greater corrosion resistance compared to ferrous metals. This characteristic is largely due to the absence of iron in non-ferrous alloys. Iron is prone to rust and corrosion when exposed to moisture and oxygen, which can significantly limit its lifespan in certain environments. Non-ferrous metals, such as aluminum, copper, and titanium, are often more stable and durable under corrosive conditions, making them suitable for a wide range of applications where durability and long-term performance are critical.

While some non-ferrous metals may have higher melting points, the distinction generally sought in this question is in their resistance to corrosion. Non-ferrous metals are also not necessarily lower in cost, as some can be quite expensive, and they do not typically exhibit better magnetic properties than ferrous metals, which possess ferromagnetic qualities. Thus, the distinguishing advantage lies in their enhanced ability to withstand corrosion.
