The low temperature thermal expansion of several aluminium, nickel, copper, and iron base alloys was measured from liquid hydrogen temperature to room temperature. Both the thermal contraction from room temperature, (L293 - LT)/Lz93, and the thermal expan- sion coefficient, (1/Lz93)I (dL/dT), are tabulated as a function of temperature.
