    Tantalum Rod is made according to ASTM B365. Pure tantalum rods are available in 99.95% and 99.99% purity. We can also provide tantalum alloy rods, the common ones are Ta10W and Ta2.5W Rods.

  • Inquiry

    The tantalum and tantalum alloy sheets are according to ASTM B708. Pure tantalum sheets are available in 99.9%-99.999% purity. We can also provide tantalum tungsten alloys such as Ta10W sheets and Ta2.5W sheets at a competitive price.

  • Inquiry

    Tantalum crucible is made of high-purity tantalum metal, including seamless and welded tantalum crucible. Tantalum crucibles are mainly used for the melting of corrosive materials and the growth of crystals since tantalum has strong corrosion resistance.

  • Inquiry

    Tantalum tubes can be produced as welded and seamless, which have a wide range of uses. The manufacture of seamless pipes is to uses extrusion, pipe reduction, or deep drawing with sheet metal. Pure tantalum sheets are available in 99.95% and 99.99% purity. We can also provide tantalum alloy rods, the common ones are Ta10W  and Ta2.5W Rods.

  • Inquiry

    Tantalum capillary, also named tantalum micro tubing and tantalum fine tube, is the tantalum tube with very small dimensions. It can be used as the filament lead tube of the cathode insulator in an x-ray tube, as a marker band in medicine, and can be used as a thermocouple tube.

  • Inquiry

    Spherical tantalum (Ta) powder is made by the Aerosol polarization method, which has high purity hypoxia, high sphericity, smooth surface, no satellite, uniform particle size distribution, excellent flow performance, and high loose density and vibrational density. 

  • Inquiry

    Tantalum powder has a series of excellent properties such as a high melting point, low vapor pressure, good cold processing performance, high chemical stability, strong resistance to liquid metal corrosion, and a large dielectric constant of the surface oxide film. Cassifications include capacitor-grade tantalum powder, metallurgical tantalum powder, and...

Tantalum Metal and Tantalum Alloys

Tantalum is a shiny, silvery metal. Tantalum is soft when it is pure. At temperatures below 150°C, it's almost resistant to chemical attack. Thanks to an oxide film on its surface, t tantalum is virtually immune to corrosion.

Tantalum and Tantalum Alloys Applications

Tantalum is mainly used in four areas: high-temperature applications, like aircraft engines, electrical devices, like capacitors, and surgical implants, and handling corrosive chemicals. Tantalum resists corrosion and is nearly impervious to chemical attacks, for this reason, it's been employed in industry, e.g. for heat exchangers in boilers where strong acids are vaporized. Tantalum is rarely used as an alloying agent because it tends to form metals brittle.
