Specification Point 2.25C (Paper 2C Only):
Explain the uses of Aluminium, Copper, Iron and Steel in terms of their properties: the types of steel will be limited to Low-Carbon (Mild), High-Carbon and Stainless

Uses of Aluminium

Aluminium alloys are often used instead of pure aluminium to increase strength.

Uses of Iron

Uses of iron, Edexcel IGCSE Chemistry
  • Iron from the blast furnace is an alloy of about 96 percent iron, with carbon and some other impurities. It is hard, but too brittle for most uses, so most iron from the blast furnace is converted into steel by removing some of the carbon.
  • Carbon is removed from molten iron by blowing oxygen into it.
  • The oxygen reacts with the carbon, producing carbon monoxide and carbon dioxide, which escape from the molten metal. Enough oxygen is used to achieve steel with the desired carbon content.
  • Other metals are often added, such as vanadium and chromium, to produce alloys with properties suited to specific uses.
