You just contradicted yourself. Aluminium forms oxide because it's very reactive as it's group 3 in the periodic table. So aluminium is anything but inert. So Aluminium is prone to changing color from silver to grey when it oxidise. Compared to iron oxide, aluminium oxide is less prone to rusting nevertheless. But to pay few hundreds dollar for a shiny silver casing that is prone to turning grey? That is erm.... does not make sense right?
That is why I'm asking the Lian Li users group. Do their Aluminium casings turns grey due to oxidation?
its common to say that aluminium is inert as aluminium always comes with the layer of aluminium oxide as it forms a layer of Al2O3 the instant it comes into contact with air. so i may have confused you with the aluminium is inert part. anyway, the aluminium casing already has a layer of Al203 surrounding it, so its highly unlikely that it will undergo any more reaction.
so just to clear things up and be very sure, aluminium is not inert, it is the layer of Al203 that is inert.
