Tantal (Ta)
Due to its unusual corrosion behavior tantalum is often used in the construction of chemical systems. Heat exchangers, heating coils and plugs, coolers, sterilizers and chemical receptacle surfaces can be made of tantalum. It can also be used in the course of repairing enemeled containers.
Because of its good properties at high temperatures it is processed into heat conductors, heat radiation shields or parts in high vacuum ovens. Its biocompatibility makes it useful in medical technology.
Tantalum has excellent ductility and can be easily processed without producing shavings. It can only be machined with special lubricants. It can easily be welded but due to its sensitivity to oxygen and other gases this has to be done in a vacuum or with protective gas such as Argon.
Available forms:
Wire Ta-wire has been manufactured in diameters between 0,2 mm and 4,0 mm and could be supplied twisted with more cores. Available from stock are wires, annealed, in diameters of 0,5 mm and 1,0 mm
Rod Tantalum rod is produced in diameters from 3.0 mm to 63.3 mm. It is produced in lengths of 1000 mm to 2000 mm. We produce cylindrical material with diameters of 4.0 mm to 80.0 mm. Depending on size the surface is hammered or machined.
Sheets Annealed sheets are stocked in thicknesses from 0.5 mm and 3.0 mm. The maximum material size is at 850 mm x 1500 mm. Between 0.1 mm and 6.0 mm we offer sheets from production. Lengths and widths depend on the thickness.
Strip Usually Ta strips are produced according to custom specifications with thickness from 0.1 mm to 1.0 mm. It is also available in forged quality.
Foils Foils are produced between 0.01 mm and < 0.1 mm. Quality and workmanship depend on the customers specifications.
Tubes Usually we stock protection tubes, heat exchanger tubes and heating plugs in common sizes. The diameters are between 4.0 mm x 0.4 mm and 38.1 mm x 0.4 mm.
Was für Tantalos in der griechischen Mythologie eine Qual war – nämlich von Wasser und Essen umgeben zu sein, ohne etwas davon zu sich nehmen zu können, nutzt uns hier bei seinem Namensvetter Tantal zum Vorteil, denn es „widersteht“ sogar den meisten Säuren und Laugen.
Tantal hat mit 3017 °C einen der höchsten Schmelzpunkte. Dazu eine recht hohe Dichte mit 16,65 g/cm³. Diese Eigenschaften und seine Säurebeständigkeit machen es z.B. interessant für den chemischen Apparatebau. Auch für Kondensatorteile in der Mikroelektronik (Smartphone) oder für Wärmetauscher wird es verwendet. Ebenso für Implantate oder Schmuck.
Tantal kommt meist als Erz in der Verbindung mit Niob vor. (Nach Tantalos Tochter Niobe benannt)
Die größten Abbaugebiete sind: Australien Brasilien Afrika und Kanada
Achten Sie unbedingt darauf, welchen Ursprung das Ihnen angebotene Tantal hat, wir arbeiten mit lizensierten Werken zusammen und können Ihnen daher versichern nur konfliktfreies Tantal anzubieten.
Wir können Ihnen Tantal in verschiedenen Qualitäten anbieten, ebenso wie Legierungen mit Wolfram (TaW)
