Bimetal

Bimetal means two different metals joined together. Instead of being a mix of two or more metals, like alloys, bimetallic objects are made of layers of different metals.

Bimetallic strips move when they are heated up. They are the most common bimetallic objects. They are often used in electric kettles as a temperature switch.
