Ferrous components are those components that are made of metals that contain iron as the main component, such as iron, steel, and cast iron. These components are favored for their strength, durability, and magnetic properties. Ferrous components are commonly used in applications that require high strength, such as construction, automotive, and machinery industries.

Non-ferrous components, on the other hand, are those components that are made of metals that do not contain iron as the main component. These metals are typically lighter and more malleable than ferrous metals, making them suitable for applications where weight is a concern. Non-ferrous components are commonly used in applications where high corrosion resistance, conductivity, and malleability are required, such as electrical and electronic industries. Examples of non-ferrous metals include aluminum, copper, brass, bronze, zinc, and nickel.
