How does a bimetallic strip work

WebFor an analog thermostat to work, something has to move as the temperature increases or decreases. That's the job of the bimetallic strip, which is just a fancy name for two pieces … WebNov 6, 2024 · How It Works The bimetallic strip in a fire alarm is made of two metals with different expansion rates bonded together to form one piece of metal. Typically, the low-expansion side is made of a nickel-iron alloy called Invar, while the high-expansion side is an alloy of copper or nickel.
