Brass tarnishes, and aluminium corrodes, and both are very soft. I use aluminium for underwater housings, but I get it hard anodised, which changes the surface structure. Hard anodising as you would expect hardens the surface, and also renders it non-conductive to electricity. But, if you want something really hard, and really corrosion resistant, it's hard to go past a stainless such as 316.
