Material considerations and selection

I can explain how a range of factors affect material selection in industry.

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. Materials have different properties that affect their use in industry.
  2. Industries choose materials by balancing cost, performance, and sustainability.

Keywords

  • Physical properties - the characteristics of a material, such as appearance and features

  • Working properties - the way in which a material responds to an external force or certain environment; also referred to as mechanical properties

  • Performance - how well a product or material works

  • Sustainability - a product or material that has minimal environmental impact through its reuse or replenishment

Common misconception

The cheapest material is always the best choice.

Material selection involves balancing multiple factors, such as strength, durability, weight, sustainability, and ease of manufacturing; in addition to cost.

Use an example of a familiar product to use as a discussion point for material choices. For example, some bicycle frames are made of steel (strong, cost-effective), while others are made of carbon fibre (lightweight, expensive).
Teacher tip

Equipment

A collection of material samples e.g. timbers, polymers, metals, textiles, glass/ceramics is needed for Task A.
