Niobium Sheet Soft ASTM B393 (Type 2)
Thickness: 0.5mm (24ga)
This is Type 2 commercial grade Niobium, an unalloyed, high quality.
Niobium is a lustrous, grey metal with low toxicity (so low that it is safe even for those with extreme sensitivities to metal jewellery)
and virtually no susceptibility to tarnish.
Niobium is very slow to work-harden and is remarkably easy to work with. Cut with a jeweller's saw, hand-form, dap, chase or forge the metal easily. In cold working (rolling, forming, etc.), niobium can be reduced as much as 90% before requiring annealing.
