This paper gives data on the linear thermal expansion of 4 samples of aluminum and 51 samples of important aluminum alloys. The preparation, chemical composi- tion, heat treatment, etc., are included. Most of the specimens were examined from room temperature to about 500 C. Typical expansion curves of the various groups of samples are shown and discussed.
