DC,

The rod stock I found under this part number is an alloy of 90%
tungsten, 6% nickel, and 4% copper. Although it will work, it's not the
best material for Tesla coil spark gaps as it will erode much faster
than pure tungsten. A little pricey too. This material is made
specifically for EDM (electrical discharge machining).
