Cast iron is a poor heat conductor compared to copper and aluminum, and this can result in uneven heating if a cast iron pan is heated too quickly or on an undersized burner.  Cast iron has a higher heat capacity than copper but a lower heat capacity than stainless steel or aluminum. However, cast iron is denser than aluminum and stores more heat per unit volume. Additionally, cast iron pans are typically made thicker than similar sized pans of other materials. The combination of these factors results in cast iron pans being capable of storing more heat longer than copper, aluminum, or stainless steel pans.

Iron pan is a durable, chemical-free alternative to the non-stick pan, cast iron is a great conductor of heat, takes less time to cook and adds additional iron to the dishes that are cooked in it.
