A bi-metal is constructed with two dissimilar metals bonded together. The expansion factor is different in each metal. When heat is applied the bi-metal will bend in the direction of the metal with the least amount of expansion factor.
Not every relation is a function. But every function is a relation. Function is just a part of relation.

A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
It's bimetal so opens when warm releasing choke which richens mixture until warm enough to run without it.

The bimetal mechanical thermometer uses one end of a bimetallic coil connected to the housing of the device and the other end drives an indicating needle. The bimetal mechanical thermometer is often used in things like refrigerators, air conditioners and heat control.

A bimetal thermometer is two strips of different metals that have been stuck together. because the two metals will have differing rates of expansion under heat, the strip will bend towards one side. if the thermometer is colder than standard temperature, the strip will bend towards the side with a higher expansion rate, and if it is hotter, than it will bend towards the metal with the lower expansion rate. Because the expansion is a fixed property of a metal, a bimetal thermometer will have a relative accuracy because of them.

A biometallic thermometer measures temperature. It uses a differential thermal expansion of metals that are bonded together into a strip. Another name for these thermometers is differential thermometer.
It depends on the properties you want. A good chart is provided by EMS at http://www.engineeredmaterialssolutions.com/6-clad_solutions.html that lists applications and the types of bonded material to use.
