Carl -
 
Any idea of the peak current in your tank circuit?
 
Or, what are the voltage and current ratings of your HV transformer, the value of your tank cap, and the dimensions of your primary coil?

You can get alloys of copper and tungsten, in the range of 10% to 20% 
copper, which machine almost as well as free-machining brass.  They 
perform as well as pure W.  My main gap has two hollow electrodes made 
from 1 1/4 diameter stock with a 1/2 inch hole for forced air (blowing 
radially inward).  After about 20 years of use, I can't see any sign of 
wear.  Actually, brass does quite well also.
