This 1/2-hard, anodized yellow niobium round wire, the bread-&-butter of jewelry making, is ideal for creating jump rings, pendant bails, ear wires, loops and a myriad of components that embellish other findings as well as a wide variety of techniques. Metal that is 1/2-hard is partially work-hardened and will hold its shape under some stress; ideal for forming structures that will support other components. Keep in mind that hardness is changeable (by annealing or heat-hardening) and is relative among metal types (each temper will feel and handle differently from one metal to another). When finishing your pieces, also keep in mind that the harder the metal is, the brighter a finish it will take.
This pre-measured coil contains 5 ft. of wire.
Niobium is a lustrous, gray metal with low toxicity (so low that it is safe even for those with extreme sensitivities to metal jewelry) and virtually no susceptibility to tarnish. Its unique properties as a reactive metal cause niobium to take on a controllable, repeatable range of colors when exposed to various voltages in an electrically charged bath, a process called anodizaton. This wire is anodized to produce a purple color. The color will not rust and cannot be rubbed off (over time, however, its luster may dull somewhat). Wrap the tips of your pliers with tape to prevent marring the surface.
