Product Description

Thermostat bimetal strip IMPHY 108SP TB 208/110 5J20110(5J11)

(Common Name: Truflex P675R, Chace 7500,Telcon200, Kanthal 1200, IMPHY 108SP, DIN TB20110 , TB 208/110)

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.

One component layer in the thermal bimetal has a low coefficient of thermal expansion called passive layer; the other component layer has a high coefficient of thermal expansion called active layer. Sometimes, in order to get the  thermal bimetal with special properties, a third or fourth layer of metal or alloy may be added.
Generally, the passive layer is made of Invar alloy containing 34% to 50% of Ni; the active layer is made of brass, nickel, Fe-Ni-Cr, Fe-Ni-Mn and Mn-Ni-Cu alloy. Different types of thermal bimetal can be obtained by different combinations of active layer and passive layer materials, such as high temperature type, medium temperature type, low temperature type, high sensitivity type, corrosion resistant type, resistance type and quick action type.

Bimetallic 5J20110 holds very high thermal sensitivity and higher resistivity,but the modulus of elasticity and allowable stress is lower,it can improve the sensitivity of the instrument,decrease the size and increase the force.
