I first noticed the Ruthenium a year or so ago. As far as I can tell it is just another precious metal with very similar physical properties to Platinum and Iridium.

Biggest difference though is ... PRICE

Current prices in US dollars per ounce:
Platinum: $969
Iridium: $1495
Ruthenium: $255

So I can see why NGK, etc. would rather use the Ruthenium if it is just as good, and maybe better.
