Product Description

For tesla coils up to 500kV, 12" diameter x 3" height spun aluminum with ¼" center hole.

These are spun aluminum of grade 1100-O (99% pure aluminum), with a narrow seam around the diameter. The seam is overlapped metal-to-metal contact around the full diameter, which does not effect the arc's emission location. Aluminum wall thickness is approximately 1/16" (so the flat central area is about 1/8" thick, for example). Excellent for Tesla coils requiring a capacitive terminal, and for high voltage DC generators.

Our laboratory has the tooling and now offers many sizes of toroidal terminals: have a look at our PDF sheet to see other available sizes from 3 to 98 inches!

  1. Great quality toroid 5 Star Review

    Posted by on 30th Nov 2021

    I was looking for an affordable yet well made toroid for my SSTC, and this one meets my requirements. It is lightweight and sturdy, and doesn't have any sharp edges of protrusions on its surface.
