Customized Tantalum Cup Ta Cup Crucible For Tantalum Products Available

Tantalum is a sensible choice whenever high corrosion resistance is required. 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. This makes it a valuable material in a large number of chemical applications. We use our "unyielding" material, for example, to produce heat exchangers for the equipment construction sector, riveted racks for furnace construction, implants for medical technology, and capacitor components for the electronics industry.

Tantalum belongs to the group of metals with a high melting point (also called refractory metals). Refractory metals have a higher melting point than platinum (1772 °C). The binding energy between the individual atoms is particularly high. Refractory metals are also characterized by a high melting point coupled with a low vapor pressure. Besides, high density and a low coefficient of thermal expansion are also characteristic of refractory metals.

In the periodic table, tantalum is located in the same group as tungsten. With a density of 16.65 g/cm³, tantalum has a similarly high density to tungsten. However, unlike tungsten, tantalum becomes brittle in hydrogen atmospheres and is therefore sintered in a high vacuum.

Tantalum is without doubt the most resistant of the refractory metals and is resistant to all acids and bases.

CHARACTERISTICS AND APPLICATIONS

Quality characteristics

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

Outstanding resistance and excellent cold ductility

Its excellent resistance coupled with its excellent formability and weldability make tantalum the perfect material for heat exchangers. Our tantalum heat exchangers are exceptionally stable and resistant. With our many years of experience in the machining of tantalum, we are also able to manufacture complex dimensions to precisely meet your requirements.
