| Bimetal consists of two or more metallic strips with different thermal expansion bonded together. When heated up it bends in a pre-determined manner and can be used to monitor, measure or regulate heat.
Its main applications are in thermostats for room heaters or water mixing but they are also used in control devices for instance in automobiles.
Kanthal offers a wide range of some 30 standard types of thermostatic bimetal with different specific deflection, manufactured in widths ranging between 1.0–170 mm (0.039–6.63 in) and in thickness between 0.10–2.5 mm (0.0039–0.097 in).
Bimetal is also manufactured as disc material to very close tolerances which give a snap action at a given temperature. |
