Product Description

ASTM TM2 thermostatic bimetal foil

Common Name: Truflex P675R,  Chace 7500, Telcon200)
Bimetallic ASTM TM2 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.
