- raverbashing 12y agoHumm Maybe it's this one? http://en.wikipedia.org/wiki/6061_aluminium_alloy http://en.wikipedia.org/wiki/6061_aluminium_alloy (a guess from here: https://discussions.apple.com/message/8612485 https://discussions.apple.com/message/8612485) Anyway, when I'm using a wristwatch I don't have a problem with the case, but the strap is often itchy (not to the point of irritating the skin, though)
- nick_riviera 12y agoIt's possible. You can nickel treat alu to give it a consistent durable finish as alu oxide is quite easy to dent and this deposits some on the surface. Another thing I've seen is that a friend of mine's MBP has started to dissolve. It is pitted and looks burned. Turns out some people's sweat eats them as well. Probably a bad material choice if you ask me.
