When the temperature of aluminium is increased, the metal expands and this is called thermal expansion. One example of thermal extension is that if, for example, the temperature of a piece of aluminium alloy 6063 is -20 ̊C and its length is 2700 mm long, and it is heated to a temperature of 30 ̊C, it will subsequently be 2703 mm long due to thermal expansion.

Thermal expansion is normally calculated in two ways, as a linear (single dimension) or volumetric (3 dimensional) measurement. Depending on the case, each method is useful, as finding out how a beam would extend due to heat would only require a linear method, however when trying to find out how a body of liquid expands with temperature, volumetric might be best.

The coefficient of thermal expansion (CTE) refers to the rate at which a material expands with increase in temperature. More specifically, this coefficient is determined at constant pressure and without a phase change, i.e. the material is expected to still be in its solid or fluid form.. Different materials have different CTEs, which make them suited for the particular use they are selected for.
