Muon spin-rotation studies on the purest available samples of Al and Cu and on AlMn/sub x/ (x=1300, 57, and 42 ppm) down to temperatures around 50 mK show that the muons are delocalized in pure Al but increasingly localized with increasing Mn content. The temperature variations are discussed in terms of strain localization and trapping in the vicinity of the impurities. For Cu, partial delocalization is observed below 2 K, which is probably limited by elastic strains from remaining impurities.
