How about tungsten Carbide. It is used for milling tools---real hard stuff.
I am currently cutting 3/8 inch dia rods to use with my RSG for a 28KVA
Tesla coil. If I don't get any reasons not to use them, (from the list), I
will use them in place of tungsten welding rods. They are hard as he-- to
cut, but I've got a diamond blade saw that will do the job.
