Re: [TCML] Tungsten for sale

Interesting that the copper tungsten works so well for you, I was told to stay away from it. 
Maybe its your large thermal mass and extremely effective cooling? 

Thanks,

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.
