Marc's right - tungsten is best, especially in places where you only need a
bit, like on the electrodes of an RSG. However, brass and copper are great
for everything elso, because they are cheap! I have never found a place to
get tungsten carbide cheap... can you help me with this marc? I live in the
UK.
