Niobium Wire

Niobium wire production in China uses advanced forging and drawing processes. Through multiple drawing passes, the niobium wire has uniform material, refined grains and excellent mechanical properties. Intermediate annealing is performed after each drawing to maintain the ductility of the niobium wire to meet demanding industrial applications.

Among the leading niobium wire metal manufacturers in China, iTOP Metal has a strong R&D team dedicated to the development of high-performance niobium alloys and composite materials. We use advanced processes such as electron beam melting (EBM) and wire drawing to ensure the high purity and uniformity of niobium wire. We independently develop higher-precision wire drawing dies to ensure that the final diameter of the niobium wire meets strict project requirements.

Niobium has a melting point of up to 2477°C, which allows niobium to maintain good mechanical properties and chemical stability in high-temperature environments. Niobium can form a dense oxide film at high temperatures, which enhances its resistance to high-temperature oxidation and is suitable for use in extreme high-temperature environments. At the same time, niobium is one of the few metals that can exhibit superconductivity at low temperatures (such as close to absolute zero). Different grades of niobium wire are used in the electronics industry, superconductor manufacturing, aerospace, nuclear industry, chemical equipment, and medical equipment, meeting the needs of various industries for high-performance materials.

On the other hand, niobium wire is a relatively new material choice in jewelry design. With its unique color and physical properties, it has gradually gained the favor of designers and consumers. Niobium has strong oxidizability. When anodized at a specific voltage, a transparent oxide film will be generated on the surface of niobium. This oxide film can present rich colors such as blue, purple, green, gold, etc. through interference effects. These colors are not produced by pigments or coatings, but are adjusted by changing the thickness of the oxide film, so the color is bright and long-lasting.

iTOP Metal has advanced niobium wire production equipment and R&D team. We can provide customized niobium wire supply solutions according to customers’ special needs, including niobium wire and niobium alloy wire of different purities. From niobium material refining to niobium wire processing technology, we can provide comprehensive and professional support to customers in different fields.

Note: We can cut standard size Niobium Wire according to customer drawing requirements, including sizes and special shapes. For other related detailed requirements, you can also contact our technical engineer by email: sales@itopmetal.com.
