Reading: Properties of Metals: Ferrous vs Non-Ferrous

Ferrous metals contain iron as their main component, making them strong but prone to rust when exposed to moisture and oxygen. Common examples include steel and cast iron, which are magnetic and widely used in construction due to their high strength and durability. These metals can be alloyed with other elements to enhance properties like corrosion resistance, such as in stainless steel. However, without proper coatings, ferrous metals may deteriorate over time, requiring maintenance in outdoor applications. Non-ferrous metals, on the other hand, do not contain iron and are generally resistant to corrosion, making them ideal for environments with high moisture. Examples include aluminium, copper, and brass, which offer excellent conductivity for electrical wiring and lightweight strength for aerospace uses. These metals are non-magnetic and often more malleable, allowing easy shaping without breaking.

Properties like conductivity, malleability, and ductility define how metals perform in design projects. Conductivity refers to the ability to transmit heat or electricity, crucial for wiring in electronics. Malleability allows metals to be hammered into sheets, while ductility enables drawing into wires without snapping. Ferrous metals excel in strength for load-bearing structures like bridges, but require protection against rust. Non-ferrous metals, being lighter, are preferred in transportation to reduce weight and fuel consumption. Incorporating Indigenous perspectives, Aboriginal communities in the Kimberley and Pilbara regions have used natural metal properties sustainably, repurposing materials for tools that respect the land. For instance, resistant non-ferrous elements were valued for longevity in harsh environments. This knowledge promotes ethical material selection in modern design.

Year 7 students learn to select metals based on project needs, balancing strength with environmental impact. Ferrous metals support heavy-duty applications, while non-ferrous offer versatility in conductive or lightweight designs. Understanding these properties fosters innovation, integrating cultural awareness for sustainable technology. (Word count: 350)
