Hand-formed jewelry is one use. Electronic parts are another. Tensile strength is listed at 200–350 MPa. Density comes in at 8.57 g/cm³. The company sits in Baoji High-tech Development Zone. Specifications are covered in the sections below. Uses and handling are covered too. How to request a quote is explained there as well.

What Is Niobium Wire?

Niobium (Nb, atomic number 41) is one of the refractory metals. High heat is needed before it melts. This metal bends easily. Many corrosive media do not attack it. Where a fine metal filament is required, a wire drawn from it will fit. Chemical stability has to hold in that filament.

Key Features of This 0.81 mm Wire

High purity: Nb content comes in above 99.9%. Fine work needs a clean base metal, and this gives you one.
Defined size: Measured across the wire, it comes to 0.81 mm. That is 20 gauge.
Tensile strength: The specs put it at 200–350 MPa.
Density: The table gives 8.57 g/cm³. Pair that with the 0.81 mm diameter, and a single meter of wire comes to about 4.4 g. That figure is an estimate, not a measurement. Still, it helps you plan quantities.
Polished surface: The finish is smooth. Jewelry makers gain from this. Electronic parts do too.
Custom length: Your order sets the length. Every piece gets cut to it.

Applications

Jewelry: Fine niobium wire gets picked by designers for hand-shaped pieces and for wirework. Planning a design? Compare it to the 0.81 mm diameter on the list and to the polished surface of niobium wire 20 gauge.

Electronics: Electronic parts are one use on the list for this wire. It also acts as the electrode feed-through inside high-pressure sodium lamps. Thermal expansion stays close to alumina ceramic. Check that it suits your own design, though.

Grades, Purity and Alloy Options

This wire has a purity of Nb >99.9%. No grade designation appears in the data supplied. ASTM B392 and other standards are often used to set niobium grades. This page makes no claim that the wire meets any standard.

Higher-purity grades of niobium are available as well. Alloys get made too, and these include Nb-Ti, Nb-1Zr and C-103. Need another grade or alloy for your project? Send us the requirement. We will take a look.

Welding, Handling and Storage

Treat these notes as general guidance for niobium wire.

Electron beam welding in vacuum works. Another option is TIG welding inside an inert gas chamber, using argon or helium.
Above about 200 °C, niobium reacts with oxygen and nitrogen. That reaction can cause embrittlement.
Store the wire in a cool, dry place.
Gloves go on first, before you touch it. Keep grease off the surface. Oil and fingerprints should stay away too.
Leftover organic matter can turn into carbon contamination later, when the part goes through heat treatment. That can harm the metal's properties.

FAQ About Niobium Wire

Q: What size and length can I order?

A: This wire is niobium, 20 gauge. Across, it measures 0.81 mm. Niobium content sits above 99.9%, and the surface comes polished. Any length you need can be ordered, and we cut it to size.

Q: Is there a set grade for this wire?

A: The data we have gives purity as Nb >99.9%. No grade designation is listed. If you need a set grade or alloy, tell us what you require.

Q: Can niobium wire be welded?

A: Yes. The atmosphere has to be controlled tightly. Electron beam welding in vacuum works. TIG welding in argon or helium also works.

Q: Does niobium wire hold up against every acid?

A: No. Many acids leave niobium alone. Hydrofluoric acid does attack it, though. Any solution with fluoride in it will do the same. Make sure it suits your own conditions before you commit.

Q: How should I store niobium wire?

A: Store it somewhere cool and dry. Grease should not get on it, and neither should oil. Wipe off fingerprints too. Put gloves on before you touch it.
