Best type of metal for turntable platform?


I have someone that owns a CNC machine. And machine for me a metal platform to the dimensions of 16 x 13 x 3. Ive heard aluminum is a good metal vs price for vibration reduction. Does anyone have any recommendations? Any input would help. Thanks.

Personally, my choices wouldn’t include a metal plinth at all. Instead, ordered by decreasing preference: heavy marble or other stone slab; a leather bag filled with buckshot; concrete; glass; thick acrylic or Lucan, HDPE, or a couple layers of heavy rubber, like lSorbothane sheeting.
