Key Features

• Purity: Nb content above 99.9%.
• Diameter: 1.02 mm (18 gauge). Jewelry wire work and electronics work both call for this size.
• Tensile strength: 200–350 MPa. That range is what we list. Test it against your bending or coiling job. Forming steps count too, so add them in.
• Density: 8.57 g/cm³. Pick a length and this number gives you the weight.
• Surface: The finish is bright. Parts you can see on the jewelry end up looking good.
• Length: Your project sets the length. We cut to it, and that is the size you get.

Applications

Jewelry makers often pick 18 gauge niobium wire. It measures 1.02 mm across. Bright looks hold up well on that surface. Forming wire parts people can see is easier with cold working.

Some parts need 1.02 mm niobium. Electronics makers can use this wire for them. Niobium also serves as feed-through wire in certain high-pressure sodium lamps. Its thermal expansion stays close to alumina ceramic. That is what makes the job possible. Match the wire's purity and size to your design before you order.

Send us your requirements first for other uses. Examples are lighting, superconducting products or medical ones. After that we can tell you whether this wire fits.

Grade and Purity: What to Confirm

This wire is listed with a purity of Nb >99.9%. Standards like ASTM B392 are what define niobium grades. A residual resistance ratio (RRR) figure is something some buyers ask for too. You will not find a grade designation anywhere on this page. No RRR value is shown here either. If your project calls for one, tell us before you order. We can then confirm what is available.

Handling and Storage

Once the temperature passes roughly 200 °C, oxygen and nitrogen can react with niobium. The metal turns brittle after that starts. For welding or heat treatment, work in vacuum or under an inert gas. One common route is electron beam welding in vacuum. TIG welding inside a chamber filled with argon or helium is another way to go.

Sulfuric acid does not bother niobium. Hydrochloric acid leaves it alone, and nitric acid does too. Hydrofluoric acid is a different story. Solutions that contain fluoride behave the same way. Both of them attack the metal. Keep them away from the wire.

A cool, dry spot is the right place for the wire. Keep grease away from it. Oil and fingerprints too. Put gloves on whenever you touch it. Any organic residue left behind can become carbon later, when the heat treatment runs.

Be used in a wide range of industries.

FAQ

Q: Which size of this product is available to order?

A: The diameter listed is 1.02 mm (18 gauge). Nb content is above 99.9%. Length is set by your requirements. Send your request to info@chdymetal.com.

Q: Does this page list a grade or RRR value?

A: No. The listing shows purity only, Nb >99.9%. Need a set grade or an RRR value? Get in touch before you order.

Q: Does the wire work for things other than jewelry and electronics?

A: Jewelry and electronics are the applications we list. Using it for something else? Send us your requirements. We will tell you if the wire fits.

Q: What should I keep away from niobium wire?

A: Hydrofluoric acid is one thing to keep off it. So are solutions that contain fluoride. Grease and oil should not touch it either. Fingerprints too. And do not heat it in air above about 200 °C.
