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.

How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
How could a bimetallic strip perform a practical task in life?
bimetal stip is next to the contacts it make your oven,iron and air conditions unit work that is when ever the contacts touch from how high you put it and it heat up and the iron and brass bends
What is different about the two kinds of metal on the bimetallic strip of a thermostat coil?
the two dissimillar metals have different heat coefficient.on the application of heat the two mtels which are comonly bonded in shape of spiral or helix expands unevenly.that's results in diferential expansion that's unwind the expansion this differential expansion is sensed by the pointer and the differentail exapansion of the metal is shown in terms of pointer deflection on the scale as measured value............. the two dissimillar metals have different heat coefficient.on the application of heat the two mtels which are comonly bonded in shape of spiral or helix expands unevenly.that's results in diferential expansion that's unwind the expansion this differential expansion is sensed by the pointer and the differentail exapansion of the metal is shown in terms of pointer deflection on the scale as measured value.............
What is a bimetallic coin?
A bimetallic strip is often used in thermostats because it is quite simple to make and responds predictably to changes in temperature. The bimetallic strip is pretty much what it sounds like - a strip made from two metals. Inthermostatsit is common to make one side out of steel and the other out of copper - then bond them together. they are formed into a curving spiral. Different metals have different coefficients of thermal expansion so as the temperature changes, the spiral strip either curls up or uncurls as one side expands or contracts more than the other. The control isattachedto one end of the strip so that as it curls or uncurls, it rotates the control.Sometimes the control is a simple mercury switch that closes a contact whenrotatedone way and opens the contact when rotated the other. Sometimes one end is attached to a power source and the other end is connected to an electric contact, which moves as the strip curls and uncurls.You can also attach it to a pointer and have it point to temperatures on a dial.
What does the bimetallic strip do in a thermostat?
Metals expand when heated and contract when cooled. Different metals expand & contract by different amounts. Rivet together a metal that changes a lot to another metal that doesen't change as much. Then when they are expanding/contracting the composite strip ends up bending up/down. They can actually bend quite a lot and can easily be used to trigger an on/off switch.
What is a bimetic strip?
A bi-metal strip is a bimetallic strip that is used to convert temperature changes into mechanical movement. It consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
What does a bimetal thermometer do?
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.
What is a bimetallic strip used in?
Bimetal strips can be used for thermocouples. The two metals will have different expansion rates and the difference will generate a small amount of electricity. The electricity generated can be collated to a given temperature. Your mom
What two metals make up a bimetal?
Brass and Iron
A strip of two different metals joined together is called.?
A strip of two different meals joined together is called a bimetallic strip.
Contains a piece of metal that bends when its hot?
A thermostat is the most common item containing a bimetallic strip.
Why the bimetallic strip bent with the heat?
A bimetallic strip is made up of two metals (the prefix "bi-" means "two"). The two metals have different coefficients of thermal expansion.
What happens to bimetallic strip when it is heated and cooled?
The two metals have different expansion rates when the strip is heated. This means that one of the metals will expand more than the other, causing the strip to bend.
Can a bimetallic strip be made from two strips of same material?
That would be more of a unimetallic strip. No, you need to use two different metals.
How does a bi-metallic strip change in temperature?
Such a strip is made from two metals with different expansion coefficients. When temperature changes it bends because of the different expansion of the two sides
Why does a bimetallic strip consist of 2 metals?
A bimetallic strip consist of two metals in order to detect rapid changes in temperature. Used in conjunction with some fire alarm systems, bimetal strips will detect rapid changes in temperature using the differences in expansion rate of the two metals. As one half of the strip expands more rapidly than the other, it will cause the strip to bow or bend causing it to touch a nearby contact sensor thus activating the ' rate of rise' temperature sensor, which may or may not be tied into an alarm system.
What is two strips of different metals welded together causing the strip to bend when heated?
That's a "bi-metal" or "bi-metallic" strip.
