I baby my aluminum razors so much, I freak about losing the threads.
My bet is that brass is a softer metal, thus more susceptible to stripping and damage of various origins.
Softer than aluminium? I don't know the answer.
[/quote]I don't want to pretend I'm a metallurgist, but from what I understand, though both are alloys in their commonly used forms, and though both fall in the same BHN range in those forms, the types of aluminum alloy most often used in the wild are far stronger and resilient. I've never had an aluminum alloy fail me or not prove to be incredibly durable, and it is used all over the outdoor and exercise industries. Heck, I've used an aluminum framed bicycle for more than a decade, and it looks like the day it was purchased. I could certainly have a distorted sense of aluminum toughness, but I know I would trust aluminum threading a lot more than I would brass. It's not that I don't like brass. Brass has other positive qualities in the context of shaving, like weight and appearance.
