Tantalum Round Bar & Rod



Tantalum Round Bar & Rod

Amardeep Steel is a leading supplier of a wide range of Tantalum Round Bars and Rods in Mumbai, India. Our products are manufactured by national and international quality standards, ensuring the highest level of reliability and performance.

Tantalum is renowned for its excellent thermal conductivity, making it an essential material in the manufacturing of heating elements, vacuum tubes, and other high-temperature components. Whether you're looking for durable materials for industrial applications or specialized projects, our Tantalum Round Bars and Rods are designed to meet your needs.


Tantalum is also widely used in electronic parts because of its ability to trap leftover gases in vacuum tubes. Tantalum films provide high capacitance, which helps make devices smaller. You'll find tantalum capacitors in computers and smartphones.

One of tantalum's key features is its resistance to corrosion from acids. It can resist corrosion from aqua regia (a strong acid mixture) at temperatures below 150°C. This makes tantalum a great choice for medical devices, as it doesn't react with body fluids. We offer a variety of Tantalum Round Bars and Rods to meet our customers' needs at very reasonable prices.

Tantalum Round Bars are known for their strong resistance to acid corrosion. They are also very flexible and easy to work with, and they conduct heat and electricity well. Tantalum forms a protective oxide layer that helps prevent further reactions with harmful materials. It has a high melting point and strength and is mostly inert, except against hydrofluoric and sulfuric acids, and can be corroded by alkaline solutions.

Discover our premium tantalum products, including pipes, tubes, flanges, and fittings, known for their exceptional durability and corrosion resistance.

Our Tantalum Round Bars are precisely sized, very strong, and resistant to corrosion. They come in various sizes, and we can also customize them based on our customers' requirements. The high melting point of tantalum makes it ideal for use in superalloys, which are used in turbine blades for aircraft, nuclear reactors, missile components, and gas turbines.
