Tantalum Bars And Rods

Product Description

Overview

Tantalum Bars and Rods are metal bars made of high-purity tantalum materials, with a high melting point, high density, excellent corrosion resistance, and biocompatibility, suitable for wide application in aerospace, petrochemical, electronic engineering, biomedicine, high-temperature processing, and other fields. Especially under the core requirements of "high temperature, strong corrosion, high precision, biosafety", its irreplaceability is significant, and it is one of the key materials in high-end manufacturing and cutting-edge technology.

Advantages

• Tantalum is extremely stable in chemical properties at room temperature and can resist corrosion from most acids, alkalis, and salt solutions except for a few substances such as hydrofluoric acid and fuming sulfuric acid.
• Tantalum has a melting point of up to 2996℃ and is one of the refractory metals. It can still maintain high strength and hardness at high temperatures and is not easy to deform.
• Tantalum has good electrical and thermal conductivity, which can ensure stable transmission of current and reduce energy loss.
• Tantalum has good plasticity and can be processed by forging, rolling, stretching, and other processing techniques, and can be made into bars of various shapes and sizes.
• Tantalum is non-toxic to human tissues and has good compatibility with human cells, and will not cause rejection reactions.

Application

1. It is often processed into reactor linings, heat exchanger tubes, valve cores, agitator shafts, etc. For example, in the production of pesticides, dyes, and pharmaceutical intermediates, parts made of tantalum can prevent equipment from being corroded, extend service life, and ensure product purity.
2. It can be used to manufacture rocket engine nozzles, high-temperature resistant skeletons of missile tail fins, and high-temperature connectors of spacecraft propulsion systems.
3. It can be processed into anode and cathode leads of high-precision electron tubes, as well as ion implantation machine parts in semiconductor chip manufacturing, which can reduce electron emission losses and ensure the high-frequency performance of devices.
4. Tantalum Bars can be used as a substrate for sputtering targets after processing, and can be used to deposit tantalum films on the surface of semiconductor wafers to improve chip performance.
5. It can be used as support rods for bone nails, bone plates, artificial joint prostheses, etc., to induce bone cell growth and promote bone tissue repair.
6. It can be made into heating elements or furnace support structures for high-temperature vacuum furnaces, suitable for high-temperature sintering, smelting, and other processes of metal materials.
7. When measuring the temperature of high-temperature molten metal, the thermocouple sleeve processed from tantalum rods can withstand the corrosion and erosion of the high-temperature melt, ensuring the accuracy of temperature measurement.

Dimension

Process

①High-purity tantalum powder (purity is usually ≥99.9%) must first be cold-pressed through a mold to form a billet with a certain density.

②If tantalum ingots are used directly, they must first be forged into rod-shaped billets through a forging process to improve the internal grain structure, material density and mechanical properties.

③Hot rolling and cold rolling are carried out alternately, and annealing treatment is required in the middle to eliminate internal stress, improve the plasticity of the material, refine the dimensional accuracy, and improve the surface finish.

④Surface treatment (mechanical polishing, pickling or coating treatment) meets high-precision requirements and increases service life.

⑤Tantalum rods are turned, milled, drilled, or welded by lathes, milling machines and other equipment to meet the manufacturing requirements of complex components.

⑥Comprehensive quality inspection, such as appearance inspection, dimensional accuracy, mechanical property testing, chemical composition analysis, etc.
