A bi-metallic strip is a compound strip of metal formed by welding together two strips of metal whose coefficients of thermal expansion are different. A change in temperature causes the two metals to change in length differentially and in an amount proportional to the temperature resulting in a curvature of the bi-metalk strip. The Figures illustrate how such bi-metallic
