Why Use Aluminum for a TT Platter?

Mass I am told is a good thing when it comes to TT platters. Lloyd Walker for one extolls it's virtues and as a rule some of the better turntables like to brag about their big ..Platters. Why then would aluminum, known for it's light weight (low density) turn up as frequently as it does as a platter material. I know it is easily machined but isn't there anything better and much denser.

i would think Copper would be good. especially an alloy that is tougher (so it will not bend if dropped)
The problem of the tarnish could be overcome with plating or a coating. A highly polished (then coated) copper platter with a lead interior (more mass toward the outer rim)... Mmmm.
Or composite sandwiches. I guess it is money. Stuff like this costs a lot to make. Easier/cheaper to make a four inch thick acrylic than a one inch thick copper alloy.
