    Why is heat treatment used in manufacturing?

    Heat treatment refers to the heating or cooling of a metal or alloy to alter its properties. The metal is heated to a certain temperature, before being cooled, to harden the metal; this can make the material more suitable for its application, especially for enduring wear and tear.

    What are the types of heat treatment?

    Common types of heat treatment include:


    • Annealing - metals are heated to a specific temperature, which is maintained until transformation occurs, before being slowly cooled. Annealing hardens the metal. 
    • Normalising - normalisation involves heating ferrous materials, before removing them from the furnace to cool. 
    • Hardening - this involves hardening metals through heating and rapid cooling. 
    • Tempering - during tempering, metals are heated to a temperature below the critical point to reduce the brittleness.

    What metals are suitable for heat treatment?

    Ferrous metals, such as steel, are the most common reciprocate for heat treatments, however non-ferrous alloys can also be treated, such as copper and magnesium. Furthermore, not all metals are suitable for all types of treatment.
