Super Conductor is a “damascus” type metal formed with copper and Niobium. Each token has a semi polished finish to it, with all machine lines removed. Niobium can be electro anodzied if you wish to add color. We do not have capsules for this size at this time.

Avaliable in large and small fillament size. (see picture)

Laser Engraving advise:

Copper and Niobium offers a unique combination for laser engraving.

Copper needs alot of power and a low frequency setting, while niobium engraves similar to titanium and becomes rough with low freq and high power. I have found a high freq and medium power setting can engrave the niobium cleanly while at the same time leave the copper almost intact. This provides a unique circumstance where the niobium can be engraved to a deeper depth than the copper ( see last picture as an example of this effect.)
