- work hardening (aka strain hardening)
- Work hardening is when a metal becomes harder due to manipulation (technically known as plastic deformation). Bending, coiling, hammering metal will harden it. This is because the manipulation changes the crystal structure within the metal. Aluminium and pure copper can only be strengthened via work hardening.
