The Copper Connection Podcast – Season 2, Episode 4

On this episode of The Copper Connection Podcast, host Chris Bailey takes a closer look at the key properties that determine how materials perform in building services engineering. From tensile strength and conductivity to ductility, malleability, and thermal expansion, we’ll unpack what each property means in practice — and why it matters when designing plumbing, HVAC, and electrical systems.

You’ll learn how these material behaviours impact safety, reliability, and efficiency in real-world installations. Plus, we’ll explore simple examples and ask the big question: how do engineers match the right material to the right job?

Whether you’re studying construction science or working in the field, this episode gives you the tools to understand why materials behave the way they do — and how that shapes the systems that keep our buildings running.

• How to explain the difference between tensile, compressive, and impact strength.
• Why ductility and malleability make copper and steel ideal for cables and sheets.
• How conductivity affects both electrical safety and thermal efficiency.
• Why thermal expansion must be considered in long pipe and cable runs.
• How material properties guide engineers in selecting the right material for the right job.

Whether you’re preparing for exams or working on site, this episode gives you practical insight into why materials behave the way they do — and how those behaviours shape the systems that keep buildings safe and functional.
