Tantalum Round Bar

Product Introduction

The Tantalum Round Bar is a premium refractory metal product known for its exceptional corrosion resistance, high melting point (over 2996°C), and excellent formability. Manufactured from high-purity tantalum ingots through precision forging, rolling, and annealing processes, it maintains outstanding mechanical stability even under extreme conditions. With its superior resistance to acids and oxidation, the Tantalum Round Bar is widely used in chemical equipment, aerospace structures, electronic components, and medical instruments. Shaanxi Chuanghui Daye Metal Material Co., Ltd. produces Tantalum Round Bars in full accordance with ASTM B365 and other international standards, offering consistent quality, precise dimensions, and customizable specifications to meet the diverse needs of global industries.

Chdymetal can offer tantalum round bar with various purities and sizes. 

Grade: R05200 / R05400

Diameter: 2-100mm

Standard: ASTM B 365

Delivery time: stock size will arrange within 1-3 days, normal production time about 15 working day.

Application Advantages

One of the main uses of tantalum is in the production of electronic components. An oxide layer which forms on the surface of tantalum can act as an insulating (dielectric) layer. Because tantalum can be used to coat other metals with a very thin layer, a high capacitance can be achieved in a small volume. This makes tantalum capacitors attractive for portable electronics such as mobile phones.

Be used in a wide range of industries.

Manufacturing & Process Flow

The production of the Tantalum Round Bar follows a strict sequence to guarantee precision and consistency:

1. Raw Material Selection – Only high-purity tantalum ingots are chosen.
2. Vacuum Melting – Electron beam or powder metallurgy melting ensures purity and homogeneity.
3. Forging and Rolling – Hot forging and rotary rolling improve strength and refine the grain structure.
4. Annealing – Controlled annealing relieves internal stress and enhances ductility.
5. Precision Machining – Final turning, straightening, and polishing achieve exact dimensions and smooth surfaces.
6. Inspection and Packaging – 100% quality inspection before export to ensure flawless performance.
