1. An object consisting of two metals.

   “Thermostatic Bimetals: Thermostatic bimetals are laminated composites using materials with a pronounced difference in thermal expansion'. Therefore, thermostatic bimetals change their shape whenever ambient temperature changes.”

   “The application of bimetals synthesized with the combination of another secondary metal such as Ni, Pd, or Pt [comprise of a high reduction potential than ZVI; ZVI, −0.44 V; Ni,−0.257 V; Pd, 0.915 V; or Pt, 1.188 V; Arning and Minteer[…]”

   “The bimetals can be used in forms such as the deflection of a straight strip, the rotation of spirals or helices and the snap action of dished discs. Applications include temperature indicators, thermostatic controls, energy regulators,[…]”
