Study Notes
Ferrous and Non-Ferrous Metals
- The main difference between ferrous and non-ferrous metals is the presence of iron: ferrous metals contain iron, while non-ferrous metals do not.
- Ferrous metals are prone to rusting, whereas non-ferrous metals are resistant to corrosion.
Types of Steel
- Stainless steel is known for its resistance against rust due to the presence of chromium, which forms a protective layer.
- Stainless steel is ideal for architectural and structural uses due to its strength, durability, and resistance to corrosion.
Preventing Corrosion
- Zinc is often used as a coating to prevent steel from corroding, as it acts as a sacrificial anode, corroding instead of the steel.
Properties of Copper
- Copper is a highly ductile and malleable non-ferrous metal, making it suitable for various applications.
- One of the main uses of copper is in electrical wiring, due to its high electrical conductivity.
Properties of Aluminium
- Aluminium is highly valued for its low density and high strength-to-weight ratio, making it ideal for applications in aerospace.
Historical Events
- The end of the Stone Age and the start of the Copper Age was marked by the discovery of copper around 6,000 years ago.
- The use of bronze, an alloy of copper and tin, began to increase around 1,200 BC.
Alloys
- An alloy is a mixture of two or more metals, often created to enhance the properties of the individual metals, such as strength, durability, or corrosion resistance.
