What light metal is used in cooking pans that heats and cools quickly?

The light metal commonly used in cooking pans that heats and cools quickly is aluminum.

Here's why:

* Lightweight: Aluminum is a very lightweight metal, making it easy to handle and maneuver.

* High Thermal Conductivity: Aluminum conducts heat very well, meaning it heats up quickly and distributes heat evenly across the pan. This allows for faster cooking times.

* Affordable: Aluminum is relatively inexpensive compared to other metals used in cookware.

While other metals like copper also have excellent heat conductivity, they are significantly more expensive.
