I usually use .032 inch aluminum for the electrical plates that will be powder coated. I could cut much thicker aluminum but using this thickness, I can cut 5 to 7 sheets in a stack.
If I am cutting steel, I usually use 24 gauge cold rolled steel (mainly because it is easily available in this size) and cut 2 sheets at a time, often with 1 sheet of 16 ounce copper or 3 sheets of .032 aluminum in the same stack.
If I am cutting only 16 ounce copper, I cut 3 sheets in a stack.
I have a book out titled "Scroll Sawing in Metal" published by Schiffer Press. Although I wrote the book, my friend Frank Pozsgai is listed as the primary author.
At the time I wrote the book, skip tooth scroll saw blades were much more expensive so I tried to make blades last as long as possible. In the book, I used "Elmer's" School glue gel between each metal in the stack. This cut down on vibration and helped lubricate the blade. It was messy and had to be washed off right away after the metal cut outs were done.
Scroll saw blades became much more inexpensive after I had written the book. Now I stack the metal between two sheets of 1/4 inch plywood and wrap it up with clear wide packing tape. (Alternate wrapping direction and side to avoid warping.)
Hope this helps
