Re: [TCML] Molybdenum electrodes

["Carl Noggle" <cn@xxxxx>]

Hey---

Molybdenum should be an excellent electrode material due to its high melting 
point.  It can be machined relatively easily with carbide tools.  And like 
you say, it is cool and exotic, and in our business, that's important.

We should keep in mind copper-tungsten alloys, which are relatively cheap 
and many of which machine about like free-machining brass.  I can aver that 
a 85% W and 15%Cu machines well and stands a few megacoulombs of sparks with 
no visible wear.

Greetings all.
    Anyone on list ever use Molybdenum for spark gap electrodes?  I'm just
curious, it looks to have some decent properties, and where I found it is a
tad cheaper than tungsten.  Plus it sounds so exotic, who wouldn't want
that material in their high voltage devices...
