Premium Tantalum Tube – ASTM B521 High-Purity Pipe for Chemical & Electronic Applications

The Tantalum Tube offered by Shaanxi Nickel Titanium Copper Metal Co., Ltd. is a high-purity refractory metal product manufactured in accordance with ASTM B521. Engineered for extreme corrosion resistance, high thermal stability, and excellent biocompatibility, our tantalum tubes are widely used in the chemical, semiconductor, aerospace, and medical industries.

Made from 99.95% or higher purity tantalum, these tubes offer unmatched resistance to acids, bases, and oxidizing environments, especially at elevated temperatures. Each tube is produced using vacuum sintering or electron beam melting followed by precision extrusion, drawing, or deep hole boring, ensuring tight dimensional control and flawless surface finish.

Tantalum’s ductility and creep resistance make it ideal for deep drawing, rolling, or tube forming without embrittlement.

🏭 Production Methods

Our tantalum tubes are fabricated using either:

Seamless Tube (Cold Drawn) – Achieved through rod piercing, extrusion, and multiple drawing steps, best for ultra-pure vacuum or pressure applications.
Welded Tube – Rolled tantalum sheet is TIG-welded, then annealed and tested, ideal for general-purpose corrosion-resistant applications.

Each tube is vacuum annealed and then non-destructively tested (ultrasonic, eddy current, or hydrostatic pressure) per ASTM protocols.
