As someone else commented "Transparent Aluminium" is really a term from Star Trek. And even in that fictional universe, it isn't pure aluminium, it's a material with some of the attributes of aluminium (density, say) but transparent.

However, if someone talks about a screen cover of transparent aluminium, my bet is that they mean a sapphire (Al2O3) cover, for its scratch-resistance.
