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.

Viridian thanks for the trademark education but Michell platters are Carbon infused acrylic that DO contain Vynil.

I was under the impression the weight of the platter was more for maintaining a steady constant speed thru inertia so the motor is less taxed in the quotient.
I never understood aluminum either, is it not a quality of the platter to allow the vibrations to be drained and not reflected back at the stylus interfearing with its purpose that one would want.

Many people call any platter not metal, acrylic which is not a true description. The platters infused with carbon and nylon known as Derlan are as the manufacturers claim closer to that of the vynil itself.
Maybe your question is really the answer to what material has not been tried for a record mat and why.

No Viridian it was not missed at all. As usual your need to be better and smarter than anyone else came radiating above all others. My apologies for insulting your imperical command of both language and knowledge.
