The linear thermal expansion coefficient is the ratio c hange in length per degree temperature to length. Linear thermal expansion for some common metals: T (oC) = 5/9 [T (oF) - 32] 1 in (inch) = 25.4 mm. 1 ft (foot) = 0.3048 m.

Linear thermal expansion coefficient is defined as material's fractional change in length divided by the change in temperature. Coefficient of linear thermal expansion is designated by the symbol α (alpha). The SI unit of thermal expansion coefficient is (°C) -1 and U.S. customary unit is (°F) -1.
Linear temperature expansion coefficients for common materials like aluminum, copper, glass, iron and many more. When an object is heated or cooled, its length change by an amount proportional to the original length and the change in temperature. Calculate thermal expansion.
The coefficient of linear expansion of Aluminium is about 22 x (10 -6) m/mC or 22 x 0.000001 per unit-length per degree C of temperature rise. Or re-stating, aluminum siding will expand along its length from 21 to about 24 micrometers (about 22 um) per meter of length for each 1°C increase in its temperature.
Radiograph Interpretation - Castings. The major objective of radiographic testing of castings is the disclosure of defects that adversely affect the strength of the product. Castings are a product form that often receive radiographic inspection since many of the defects produced by the casting process are volumetric in nature, and are thus ...
