aluminum has its own corrosion through oxidation. this happens in contact with the air and when it is in contact with different metals, especially ferrous ones where that corrosion will take a lot more than some heat to break. ever had a wheel seize to the hub? raw aluminum wheel plus the iron top hat of the rotor....yea not fun, even my 10lb sledge wasn't making progress.
but to everyone else, overall, i imagine both will last just fine...corrosion is a factor to some degree in both materials. we've all been there, we all get through it.
i think, just my speculation, that the aluminum may reduce road feel but make turn in sharper and the car respond better....being lighter yet just as stiff, or stiffer + "insert essay about unsprung weight here"
my '18 mustang gt has a lot of aluminum in the suspension, and i am not worried about it at all....much heavier, and much faster car with 460 whatever hp. i can only speculate that part of its numbess in road feel is the aluminum but then again my e39 had the same amount or more of aluminum suspension components and it had incredibly good road feel so its probably the epas making the mustang feel numb. (and the e39 was the v8 540 fwiw)
overall, aluminum, even just a couple pounds saved, should make the front end a little more responsive and sharp would be my conclusion....ymmv. i suspect it will be a very small difference that 99% won't notice but they will claim its night and day.
