Metals thermal expansion
WebDifferent types of metals expand to different extents when experiencing a rise in temperature and vice versa. When two metal strips with varying thermal expansion rates are bonded together, the upper strip is partly prevented from expanding by the lower strip when heated. The resulting force causes the linked strips to bend.

The thermal expansion of α-SiC is nearly linear over a wide range of temperature. The expansivity is 4.5×10 −6 C −1 from 20 °C to 1000 °C and 5.5×10 −6 °C −1 from 20 °C to 1500 °C. This is lower than the expansivity for refractory oxides and much lower than most metals. Specific heat.
WebSome bimetals include a third layer of copper or nickel in between the active and passive sides in order to increase thermal conductivity and decrease the material’s electrical resistivity [1, 2]. Properties of bimetal. Bimetals work with the propensity of metals to expand when heated, and contract when cooled.
