@slaw,
Thank you for the clarification. I guess SME got me covered, here is the description from their website, the Model 15 platter is
“Machined from aluminium alloy and weighs over 4.6 kg (10 lbs). It is extensionally damped, the top surface being diamond-turned with a fine scroll. This method of finishing contacts a myriad of tiny fibres with the underside of the record, firmly coupling it to the platter”.
And they suggest to avoid anything that might scratch the turntable platter. The material is as delicate as a record itself and very easily damaged.
