Superconductor - Full - Circle

Full round slice of superconductor: niobium–titanium (NbTi) filaments in a copper matrix.

A regular filament pattern across the whole face. The filaments run through the full thickness, so the pattern stays clean as you contour and shape.

Sized for bolsters, inlays, pivot collars and jewellery.

Spec: Approx. 90 g, 0.182 in thick. The photo shows a representative slice from this grade, on a cutting grid for scale.

Maker's notes

• The silver-and-copper contrast is in the metal itself. No etching is needed.
• Copper loads abrasives quickly. Use fresh belts and light pressure.
• The slice conducts heat well and gets hot fast while grinding. Work in short passes and let it cool.
• Bare copper develops a patina with handling. Let it age, or seal it to keep the bright finish.
