TheDefinitionandOperatingPrincipleofBimetals:
Bimetal is bonding by two or more different expansion coefficients metal or alloy, whose shape changes at changing temperature.
1.The active side of the bimetal requests large expansion coefficients, high melting point and similar modulus of elasticity with the passive side, And, there are many choices for the raw material of the active side, such as resisto, nickel-ironmanganese, manganin, pure nickel, pure iron, brase, bronze, stainless steel, etc. Commonly used are Mn72Cu18Ni10, Ni22Cr3, Ni20Mn6, Ni18Cr11, Ni19Cr2, Ni25Cr8, etc.
2.The passive side of the bimetal usually is the ferro-nickel with low expansion coefficients. In 1896, Guillaume invented the invarwhich having low expansion coefficients, at the room temperature only about 1.2*10-6/ ℃. It built up the foundation for the bimetal development. Commonly used are Ni36Fe, Ni39Fe, Ni40Fe, Ni42Fe, Ni45Fe and Ni50Fe.
3.In order to attain different resistivity among the bimetal, we usually put in the lower resistivity metal between the active and passive side to affect the resistivity, such as pure Nickel, pure Copper, Zirconium-Copper, etc.

3.The temperature range of application is a little larger than the linear temperature range. Within this range, bimetal with free deformation will not present the residual deformation. While beyond that range, the bimetal material's expansion coefficient will have a great change so that the sensitive of the bimetal will be decreased. But it still can be used. And this temperature is generally lower than the curie point, of the material, since the material structure and performance will change once reached the Curie point.
