Heat distribution. Both are excellent heat conductors; so they encourage the heat from the flame/coils to spread out evenly over the bottom of the pan.
By the way, copper and aluminum are relatively soft metals; so contrary what you might read elsewhere, they do not hold their shapes as well as the iron they are attached to. That's one reason pans have iron bodies even though they might have copper or aluminum bottoms. Iron is also cheaper than the other two metals.

The purpose is to distribute the heat evenly on the bottom of the pan/kettle.

Being better conducters of heat, they absorb heat relatively faster and helps in saving both time and fuel.

It helps in heat distribution.

copper and aluminum are very good conductors of heat ... and they do not lose their shape as easily as steel
