Bimetallic Device

Bimetallic Device for Education – Demonstration Tool for Thermal Expansion

The bimetallic strip is a strip composed of two metals (copper and steel, an iron alloy) with different coefficients of thermal expansion and mounted on a wooden handle. The parts are riveted together. When the strip is heated briefly with a small flame, it rapidly curls, providing a simple and effective demonstration of the unequal expansion of the two metals (one pulls the other). This striking teaching aid is ideal for demonstrating metal properties in physics and science lessons at schools. Length/width: 20 x 1,5 cm.
