5J14 Thermostatic Bimetal (Thermal Bimetal Strip)

5J14 is a Chinese thermostatic bimetal material consisting of a high-expansion layer (generally a copper-zinc alloy) bonded to a low-expansion layer (a nickel-iron alloy). It offers good thermal sensitivity, producing visible bending deflection with temperature change, together with adequate strength and toughness for a wide range of temperature-control applications.
