I thought that the main problem with aluminum wire, at least back in the 70s when they used it in houses, was that it expanded under the screws holding it to receptacles and caused the screws to back out, creating a gap and resulting heat and fires. their cure was to use a piece of copper wire at the receptacle and hooked that up to the main run of aluminum.
IIRC, these were all retrofit in older houses and it was cheaper to add a couple of inches of copper wire than replacing all of the receptacles.
