Conference paper


Since World War II various attempts have been made to successfully substitute aluminum for brass in cartridge cases. Only partial success has been achieved; the main problem appears to be burn throughs which infrequently occur in the side wall of the cases. The nature of the failure is such that (i) severe damage occurs to the weapon upon burn-through and (ii) failure analysis is difficult. The general interpretation is that small tears occur during the cupping operation which are obscured by subsequent forming operations.
