Why Do Some Materials Transfer Heat Better Than Others

This series was filmed and edited by Keaton Bowlby

Why does aluminum transfer heat so much faster than steel?

In this episode, Jake breaks down the engineering behind thermal conductivity and what actually causes heat to move through a material. From Fourier’s Law to what’s happening at the atomic level, you’ll learn why different materials transfer heat at different rates and how that can affect the material you choose for your parts.

Things we cover:

  • What thermal conductivity actually is
  • How heat moves through a material
  • Fourier’s Law explained simply
  • What affects the rate of heat transfer
  • Why aluminum transfers heat faster than steel
  • What’s happening at the atomic level
  • How thermal conductivity affects material choice
