Metal properties, sources and stock forms

I can describe where different materials come from and identify their common stock forms.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Raw materials need to be sourced and processed into a useable form.
  2. Metals are sourced from the earth as ores, which are mined, extracted, and processed into usable materials.
  3. Metals are categorised as ferrous, non-ferrous, or alloys.
  4. Processed metals are formed into standard stock forms.
  5. Metal properties such as strength, ductility and conductivity determine their suitability for different products.

Keywords

  • Metal - a shiny, solid material

  • Properties - the characteristics of a material that determine how it looks, feels, and behaves when used

  • Stock form - the standard shapes and sizes in which materials like metals are supplied

Common misconception

All metals have similar properties.

When metals are grouped into ferrous, non-ferrous, and alloy metals, their properties are different.
