Thermal Bimetal Strip 2036S25 for Fuseless breakers

 

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.

 

The basic characteristic of the thermal bimetal is changing with temperature and temperature deformation, resulting in a certain moment.Many devices use this feature to convert heat energy into mechanical work to achieve automatic control.Thermal bimetal used for control system and temperature sensor in the measuring instrument.


Main features: Linear temperature range is higher, low thermal performance, can be used at high temperature.

production process


Cold rolled →go oil → pickling → annealing cold-rolled →oil → pickling → annealing cold-rolled → conform to the requirements of the use of thermal bimetal strip

 

Thermal bimetal strip is by the different expansion coefficient of two or more than two layers of metal or metal solid combination, and along the entire interface varies with temperature and the thermal function of shape changes in composite materials.One of high expansion coefficient become active layer, low expansion coefficient becomes passive.When requirements with high resistivity, but heat sensitive resistance performance is essentially the same type of thermal bimetal series, can be added between the two layers of different thickness of middle layer as a shunt layer, is to achieve the purpose of control different resistivity.
