Rotating-specimen measurements of the annihilation radiation have been carried out to investigate the Fermi surface of α Cu-Al alloys up to 15.5 at % Al. The conventional angular-correlation measurements along the [100] axis have also been performed in a long-slit geometry. The Fermi surface of α Cu-Al alloys has been found to be similar in shape to that of Cu. A trend of the monotonical increase with Al concentration has been found both in the size of <111> neck and in the <100> Fermi momentum. The change in the Fermi surface of this alloy follows closely that of α-brass with the same e/a.
