Ruthenium, like all platinum group metals, is to create a catalyst. This metal is added to alloys to improve corrosion resistance, strength and hardness of the alloy. Thermocouples ruthenium in combination with iridium used to determine the highest temperatures. In some cases, ruthenium is added in the tips of the handles for durability.
