What are The Uses of Tantalum

Tantalum's corrosion resistance

Tantalum is a sensible choice whenever high corrosion resistance is required. This platinum-gray-colored metal has a density of 16.6 g/cm3 which is twice as dense as steel. We use our "unyielding" material, for example, to produce heat exchangers for the equipment construction sector, charge carriers for furnace construction, implants for medical technology, and capacitor components for the electronics industry. Tantalum's corrosion resistance makes it a valuable material in a large number of chemical applications.

Tantalum's excellent thermal and electrical conductor properties

Also, it is highly ductile at high temperatures, very hard, and has excellent thermal and electrical conductor properties. Its melting point of 2,996°C is the fourth highest of all metals. Even though tantalum is not one of the noble metals, it is comparable to them in terms of chemical resistance. In addition, tantalum is very easy to work at well below room temperature despite its body-centered cubic crystal structure.

With its combination of specific physical and chemical properties, tantalum is an important product in many applications:

Tantalum features a high degree of biocompatibility. For this reason, it is used in medical technology as a radiographic contrast agent and in the production of bone replacement material and implants.

In the aerospace and energy industries, tantalum increases the corrosion resistance of alloys in turbine blades.

Tantalum's chemical corrosion and high-temperature resistance properties provide many benefits to the chemical process industry. For this reason, tantalum is used in the production of reactor coatings, heat exchangers, and pipelines.

Its ability to form an extremely thin oxide coating which provides a protection layer makes tantalum the material of choice in the production of small, high-quality capacitors.

A wide variety of tantalum compounds provide outstanding material properties that are of critical importance for modern, advanced industrial applications:

Due to its particularly fine microstructure, tantalum is the perfect material for drawing ultra-slender wires with a flawless, exceptionally pure surface for use in tantalum capacitors. We can determine the chemical, electrical and mechanical properties of these wires to a high degree of precision.

During the production of tool and cutting steels that contain carbides, tantalum, and niobium carbide are added to increase performance and stability.

Manufacturers of optical lenses use tantalum oxides to improve the refractive index of their products allowing for thinner lens profiles.

The wide variety of industrial applications in which our tantalum is used reflect the unique properties of the material.

Its excellent resistance coupled with its excellent formability and weldability makes tantalum the perfect material for heat exchangers. Our tantalum heat exchangers are exceptionally stable and resistant to a range of aggressors.
