Spark gap metals

Why are ya'll so concerned about the metal your spark gaps are made of?
As long as your the metal has enough surface area( to radiate heat) and you 
keep blowig air on it(like with a muffin man... I mean fan), it won't melt 
and it would be fine.
You could even make a fine spark gap by replacing the copper pipes or 
tungsten rods with old heat sinks from scrap computers.Besides, isn't 
tungsten expensive?
Trust me, I may be new at this, but I can tell you that fan cooled heat 
sinks or at least copper pipe(the longer the better) will do just as good, 
if not better, than tungsten rods.
Also, the tungsten rods have less surface area than a copper pipe and 
therefore more likely to get really hot, and even though tungsten cand 
stand more heat, it doesn't need to as long as you cool it right. Tungsten 
rods are just a waste of money and tungsten.
