Product Details
Thermal bimetal is a kind of precision alloy, consists of two layers (or layers) with different thermal expansion coefficient of metal or alloy layer components as solid combination and into.A group of thermal bimetal yuan layer with low thermal expansion coefficient, the passive layer;Another group of yuan layer with high thermal expansion coefficient, to active layer.Sometimes, in order to obtain special properties of thermal bimetal, can also join the third or fourth layer metal or alloy.Usually, the passive layer are type invar alloy containing Ni34 ~ 50%;Active layer, the brass, Ni, Fe - Ni - Cr, Fe - Ni - Mn and Mn - Ni - Cu alloy, etc.Through different combination of active and passive layer material, you can get different kinds of thermal bimetal, such as high temperature, medium temperature, low temperature, high sensitive, corrosion resistant, resistance and quick action, etc.
application
Bimetallic strip: thermal bimetal is composed of two or more than
two layers have different linear expansion coefficient of solid
combination of alloy composite materials.Large expansion coefficient of the alloy layer is called the active
layer, smaller expansion coefficient of the alloy layer is called
the passive layer, between active and passive layer can be adjusted
with the middle tier of the role of resistance, when the
environment temperature changes, because the expansion coefficient
of active and passive layer, bending or rotation.This alloy is used for temperature control, temperature
compensation, current limit and temperature indicating temperature
sensor in automatic control equipment and instrumentation.Can also
be applied to the circuit breaker, switch, thermal relay, all kinds
of temperature control components, home appliance protector,
electronic protector, overload protector, condensate drain device,
temperature controller, thermometer, incubator, meteorological
instruments, electric iron, electric rice cooker, refrigerator,
fire alarm, fluorescent lamp, oven, lighter, the starter current
mode control switch automatically, automatic protection switching
rules, etc.Also used for fluid (gas, liquid) valve temperature
sensor in low voltage electrical switches, etc.
