Can a stip of metal or metals bend due to electricity running through it?

In phyics class I saw that a strip of metals made up of two diffferent metals bend because the metals expand at different rates. Is there a metal or metals that bend due to electricity running through them? Is this possible? What kind of metals?

1. Electricity heats the metals; heat bends them.
2. any metal which heats because of internal resistances should bend or curl. Extreme heat. I would say ordinary sheet metal of steel would do it quite easily. Copper and other metals maybe not so much. Some metals might just act like fuses and burn open...like copper.
