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.

The idea of "big" or extremely heavy platters is mostly for use with belt drive tables which I believe, in terms of speed accuracy, are clearly inferior to properly implemented direct drive tables.

And yes, when it comes to belt drive, it is about inertia. "An object in motion remains in motion unless acted upon by an outside force".
