Tantalum Niobium Alloy Wire

Product Introduction

Tantalum-niobium alloy is a tantalum-based alloy with the addition of niobium. Common types of tantalum-niobium alloys include UNS R05240 Ta40Nb, Ta3Nb, Ta20Nb, and Ta30Nb alloys.

60%Tantalum 40%Niobium (Ta40Nb)is one of the most commonly used grades ,can be made into different shapes such as pipe, rod and wire. Ta-40Nb alloy has the advantages of high melting point, corrosion resistance and good cold processing. It is widely used in chemical, atomic, aerospace and other industrial fields.

Manufacturing & Process Flow

Each Tantalum Niobium Alloy Wire is manufactured under a tightly controlled process to ensure purity, uniformity, and precision.

Process Flow:

1. Raw Material Selection and Alloy Blending – Strict testing and proportioning of tantalum and niobium raw materials.
2. Electron Beam or Vacuum Arc Melting – Ensures purity and homogeneity of the alloy.
3. Hot Forging and Rolling – Refines grain structure and improves mechanical properties.
4. Cold Drawing and Annealing – Achieves fine tolerance and optimal ductility.
5. Straightening and Surface Polishing – Produces clean, oxide-free, and bright surfaces.
6. Dimensional and Mechanical Testing – Verifies compliance with ASTM and ISO standards.
7. Final Inspection and Secure Packaging.
