EXTREMELY RARE Superconductor Copper Niobium Metal Alloy (Beehive Pattern) from the ex-Texas Superconducting Super Collider / DESERTRON

* Raw metal alloy material (see ULTRA-FINE NbTi FILAMENTS on the first detailed picture of the beehive pattern) for knife bolsters, jewelry, ornaments, etc... see pictures how to anodize it. * Cut from the sample runs of the main conductor rods of the ex-Texas Superconducting Super Collider a.k.a Desertron that was started years ago. The project was scrapped due to budget cuts. (WIKI: https://en.wikipedia.org/wiki/Superconducting_Super_Collider). * The piece is a slice of Niobium Titanium (NbTi) superconductor preform / half made wire for Rutherford cable. It has approx 6,426 twisted NbTi filaments with a diameter of 6-micrometers (10 times thinner than a normal human hair) embedded in an oxygen free copper matrix. Around each filament there is a 0.0005 mm layer of high-purity copper. Copper is an insulation material between the filaments in the superconductive state, when the temperature is below -263C. When leaving the superconductive state, copper acts as a conductor transferring th
