ABSTRACT:
A three-layer metal laminate consists of only two different metals with different coefficients of thermal expansion. The two outer layers consist of the same metal, yet of different thicknesses so that, on heating the metal laminate there arises a cotrolled bimetal effect which is utilized in thin-based vessels for hot food, to maintain the base flat on being heated.
