Sheet Metal - 20ga Sheet - Unanodized Niobium (1 square inch)

Niobium is a rather uninspiring dull grey metal, until you run an electric current through it (Anodizing). Depending on the voltage, you can make it a rainbow of colours! Niobium is also hypo-allergenic. This comes pre-cut in 1 inch squares.
