Compound Metal Strip - Copper & Iron

Product Code: 1249503

To show the unequal or differential expansion of two different metals in a bimetallic strips. Comprising two strips, each of different metal but in same size, riveted together end to end and fitted on an insulated handle. On heating, the compound strip bends into curvature with metal having more coefficient of expansion on concave side and other one on convex side. Returns back to its original shape on cooling. The thickness of the two metal strips selectable carefully so as to obtain sufficient curving on applying little heat. The strip is only 1.5mm thick so that very little heat is required to produce considerable bending.
