Toroids, Terminals, and Corona Balls

 Toroids, Terminals, Corona Balls for Tesla Coils

We now offer a wide selection of toroids, oblates, corona balls, and other high voltage terminals. These are excellent for Tesla coils requiring a capacitive terminal. Our most popular professional spun 18" x 4.5" toroid is manufactured using 99% pure aluminum (1100-O grade) with a welded seam that is smoothed and polished and cannot be seen, while our other toroids are either stamped or spun, but feature a seam that is visible, which is common for most commercially produced toroids.
