[TCML] Copper Tungsten Alloy

[Matthew Edwards <matthew.n.edwards@xxxxxxxxx>]

I was wondering if anyone has tried using copper tungsten alloy for spark
gap. I have noticed some listed on ebay as grade 50-235 which appears to be
70% tungsten, 30% copper. It seems like it would be a good material to use
but I wanted to get some "expert" opinions.

According to wikipedia;

CuW alloys are used where the combination of high heat resistance, high
electrical and thermal conductivity, and low thermal expansion are needed.
Some of the applications are in electric resistance welding, as electrical
contacts, and as heat sinks. As contact material the alloy is resistant to
erosion by electric arc. WCu alloys are also used in electrodes for
electrical discharge machining and electrochemical machining.[2]

There is a chart on this page displaying the properties of the alloy.
Resistivity, etc..
