Introduction

Niobium tube is a specialized metallic pipe used for conveying and transferring materials under high-temperature and high-pressure conditions.
Thanks to niobium’s exceptional corrosion resistance, high-temperature stability, and mechanical strength, these tubes exhibit superior compressive, tensile, fatigue, and thermal resistance properties.

As a result, niobium tubes are widely applied in nuclear technology, aerospace, shipbuilding, chemical processing, and electronic industries, where reliability and performance in extreme environments are critical.

Nb2	Remainder	0.01

Surface Treatment

Common surface treatment methods for niobium tubes include:

Mechanical Polishing – Improves surface smoothness and dimensional precision.

Electrolytic Polishing – Enhances corrosion resistance and achieves a bright, mirror-like finish.

Pickling – Removes oxides, oil, and other surface contaminants to restore metallic luster.

Sandblasting – Cleans and textures the surface, improving coating adhesion and uniformity.

These treatments enhance both the appearance and corrosion resistance of niobium tubes, ensuring excellent performance in demanding environments.

Applications

Niobium tubes have diverse uses across high-technology and industrial sectors, including:

High-temperature alloys
Niobium-based alloys
Steel refining and strengthening
Electrical porcelain components
Coinage materials
Medical devices and implants
Aerospace components
Electronics and vacuum equipment
