Polished Tantalum Bar

A Polished Tantalum Bar is a high-purity (typically ≥99.95%) tantalum metal product that, following a precision surface polishing treatment, exhibits a lustrous silver-gray appearance. Characterized by exceptional corrosion resistance, a high melting point, and excellent biocompatibility, it is widely utilized in high-tech sectors such as aerospace, medical implants, advanced chemical equipment, and electronic components.

As a tantalum rods supplier with more than 20 years of professional experience, FANMETAL can not only provide customers with standardized pure tantalum or tantalum alloy products, but also provide high-precision customized products. If you have any questions about this product's details or pricing inquiries, don't hesitate to get in touch with us at admin@fanmetalloy.com. We look forward to your message.

• Table data is based on ASTM B365 (electron beam melting R05200 is the main) for bright tantalum rods (surface polished/polished).

1. Chemical equipment field

Reactor lining: A tantalum rod is used to prepare the reactor liner and stirring shaft, which can resist 98% concentrated nitric acid, sulfuric acid, hydrochloric acid, and other strong corrosive media, and the service life is 10-15 years, which is 5 times longer than that of stainless steel reactors.
Heat exchange equipment: heat exchange tubes and coils used to manufacture heat exchangers, using the high thermal conductivity and corrosion resistance of tantalum, suitable for heat transfer of corrosive media.

2. Aerospace field

Rocket engine: Niobium tungsten alloy nozzle/thrust chamber is machined from Polished Tantalum Bar, with a melting point of over 2500°C and more than twice the strength of traditional alloys.
Thermal protection system: As the leading edge skeleton of the spacecraft when re-entering the atmosphere, it maintains structural integrity in an environment of 1500-2000°C, and the thermal expansion coefficient is stable at 6.5×10⁻⁶/°C to avoid cracking caused by thermal stress.

3. Electronics industry

Tantalum Capacitors: Polishing tantalum rods is used to manufacture tantalum capacitors with high capacitance density, which are widely used in mobile phones, computers, automotive electronics, and other devices.
Semiconductor Target: As the core component of sputtering targets, metal atoms are evenly deposited on the wafer surface by bombarding tantalum targets with high pressure, forming a conductive or barrier layer to ensure the stability of chip signal transmission.
New energy applications: Pure tantalum rods are used to manufacture electrodes for electrolysis of water to hydrogen production equipment and bipolar plates for hydrogen fuel cells to ensure long-term stable operation of the equipment.

4. Medical implantation field

Orthopedic implants: Polished Tantalum Bar is made into artificial joints (such as hip joints, knee joints) and bone fixation plates through precision processing to promote bone cell growth to achieve "biological fixation" and avoid the "stress masking effect" of traditional metal implants, and clinical data show that the service life can reach 15-20 years, which is more than 50% longer than stainless steel prostheses.

(1) Select a high-purity tantalum metal billet (purity ≥99.95%) to strictly control the impurity content

(2) High-purity tantalum powder was prepared by hydrogenation → powdering→ pickling and impurity removal→ and subsequent treatment processes

(3) Press tantalum powder into bars, which requires no defects, no cracks on the surface, and a certain strength.

(4) Forging generally adopts the cold rolling process, which can be used as a billet-making process before die forging, or directly rolling tantalum billet strips.

(5) Heat treatment must be carried out in a high vacuum, and the temperature is generally 950-1300°C.

(6) Use a mixture of hydrofluoric acid, nitric acid and hydrochloric acid for pickling, and then use an ultra-fine grinding wheel to gradually achieve the polishing surface roughness.

(7) Quality control and testing, such as composition analysis, surface quality, dimensional accuracy, flaw detection testing, etc.

(8) Pack in a wooden box with plastic partitions, with material certificates, packing lists and other accessories, and the weight of a single box should not exceed 100kg

Polished Tantalum Bar, tantalum bar stock to India

Containers loaded with 99.95% high-purity bright tantalum rods recently departed from Zhengzhou International Dry Port and shipped to the port of Mumbai, India, and will be used for local semiconductor and aerospace equipment manufacturing. In the early stage, after receiving the customer's inquiry, we arranged the technical team to complete the confirmation of the dimensions and parameters with the customer within 48 hours, and completed the delivery in 6 weeks through the "vacuum melting + precision turning" process.
To meet customers' needs for purity, precision, and compliance, we provide solutions with <0.001% impurity, Ra≤0.8μm precision machining, and ASTM/SGS documents. An Indian customer praised the product's performance and plans to promote further cooperation.
