Abstract
To investigate pinholes in 8079 Aluminum foil, optical microscopy and scanning electron microscope with energy dispersive spectrometer were adopted. Results show that four types of pinholes in 8079 aluminum foil, (1) small size, rod-shaped, (2) pinhole in groove, (3) hole with big size, (4) crumpled pinholes. Big compounds along with all rolling and heat treatment processes cause the small rod-shaped pinhole. The big compound contains elements of Al-Fe-O.
