Bimetal Strip Telcon 140B/5J1480/5J18

(Common Name: Kanthal 135, Telcon 140B,FPA223-80,NEOMAX BL-5,TB 140/80,TRUFLEX B1,ASTM TM1,IMPHY R80,Dimpty R80

Bimetallic alloy,it is a kind of precision alloy bonding by two or more different expansion coefficients metal or alloy, whose shape changes at changing temperature. 


Composition:
High expansion layer:Ni22Cr3
Low expansion layer:Ni36

Typical Physical properties
Density (g/cm3):8.2
Electrical resistivity at 20ºC(mm2/m):0.8+/-5%
Thermal conductivity, λ/ W/(m*ºC):22
Elastic Modulus,  E/ Gpa:147~177
Bending K / 10-6 ºC-1(20~135ºC):14.3
Temperature bending rate  F/(20~130ºC)10-6ºC:26.2%±5%
Allowable temperature (ºC):-70~ 350

Application: The material is mainly in automatic control devices and instrumentation (eg: exhaust thermometers, thermostats, voltage regulators, temperature relay, automatic protection switching, diaphragm meters, etc.) make temperature control, temperature compensation, current limit, temperature indicator and other heat-sensitive components.

 

Feature: The basic characteristics of Thermostat Bimetallic is bending deformation with temperature changes, resulting in a certain moment.
Thermostat Bimetallic Strip expansion coefficient is different from the two or more layers of metal or alloy along the entire contact surface firmly bonded, having a temperature-dependent shape change occurs thermosensitive functional composites. Wherein the higher expansion coefficient of the active layer is a layer called a low coefficient of expansion of the layer is named passive layer.
