Furnace Igniter.. what is that wire made of? Mine erodes.

So, my furnace igniter, basically 2-3 wires sticking out over the burner where the propane comes up, is no longer in production.

Last season, I took it to a welder, who proptly welded some welding rod to extend the lengths of the electrodes, and away I went. It worked great ... for that one season.

Yesterday, I turned on the furnace and it wouldnt light. Pulled the igniter and it had eroded very quickly.

So my question is...

What metal do they make igniter electrodes from?
What metal do they make spark plugs from? Im thinking the same?

Thanks,
