Aluminum

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
This is a science community. We use the Dawkins definition of meme.
Titanium is awesome, though. Has similar corrosion properties to aluminum (in that it only oxidizes on the surface), is similar in strength to iron/steel, but is only about 60% of the weight iron. So it's lighter.
Plus if you mix in molybdenum and I think some nickel, you can have yourself a very long lasting spring that won't sag like steel springs after several years.
Main downside is it's so expensive compared to iron :(
