Tritium
This is a strong metal which has come into more common use in the fourth age. It is moderately rare and expensive, but is not as rare as amarnium. It takes a master blacksmith to work with this metal. Its color is a lustrous silver, and resists corrosion and damage. It does not interfere with magic.
