Linear Coefficient of Expansion.Heating a metal to temperatures below its melting point causes it to expand or increase in length. If a bar or rod is uniformly heated along its length, every unit of length of the bar increases. This increase per unit length per degree rise in temperature is called the coefficient of linear expansion. Where a metal will be alternately subjected to beating and cooling cycles and must maintain a certain tolerance of dimensions, a low coefficient of thermal expansion is desirable. When in contact with a metal of a different coefficient, this consideration assumes greater importance.
Titanium has a low coefficient of linear expansion which is equal to 5.0x10-6inch per inch/°F, whereas that of stainless steel is 7.8x10-6, copper 16.5x10-6, and aluminum 12.9x10-6.

∙ 9y agoYes, aluminum does expand when heated. Aluminum expands twice as much as iron when both are heated the same amount.

When buying a rosette iron for making rosette cookies which is a better tool cast iron or the aluminum iron?
Cast Iron. Cast Iron can be "seasoned" which creates a "non"-stick coating while cast Aluminum cannot. I have used both cast Iron and cast Aluminum; the rosettes made with the Aluminum irons never release as well as rosettes made using the cast Iron. Given how delicate rosettes are after frying and how HOT as well; I have never had the same success rate using the aluminum irons.
