Niobium Round Bar

Product Introduction

The Niobium Round Bar provided by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is made from high-purity niobium, offering excellent corrosion resistance, high melting point, and superior mechanical properties. Each Niobium Round Rod is precision-forged and machined to ensure consistent diameter, smooth surface finish, and reliable performance. These features make the Niobium Round Rod suitable for high-demand industrial applications where quality and durability are essential.

Niobium has a density of 8.57g/cm³, a melting point of 2477°C, and a boiling point of 4744°C. Niobium is a silver-gray, soft and ductile rare high melting point metal. Because niobium has good superconductivity, high melting point, corrosion resistance, wear resistance and other characteristics, it is widely used in steel, superconducting materials, aerospace, atomic energy and other fields.
