More info

Tantalum is easily oxidation, but its anti-corrosion is one of the highest medals, meanwhile, it has good integration with human tissues. TantalumCapillary tube is often used to make medial instruments, special instruments, etc. As its special manufacturing artwork has a big difference from other metal capillary tubes, Tantalum capillary tube is not easy to make. HM provides high-quality Tantalum (Ta) Capillary at a competitive price, which can be used in scientific research or industrial production. The most common applications of tantalum capillary tubes are tantalum marker bands and thermocouple protection tubes.

Tantalum Capillary Tubes

  • Outer diameter range: 0.2-8mm
  • Max accuracy of outer diameter: +/-0.003mm
  • Range of tube wall thickness:0.015-0.5mm
  • Max accuracy of wall thickness: +/-0.005mm
  • Max accuracy of length: +/- 0.05mm

After completion, watch with a microscope, Tantalum capillary tube has features of average metal gloss, no color changed by hydrogenation and oxidation, no scratch, no deformation, no skin needling, etc.
