Tantalum Tube
Tantalum exhibits high reactivity towards interstitials elements like Hydrogen, Nitrogen and Oxygen. Also it may react with Hydrocarbons. Its recrystallization temperature varies between 900 °C and 1450 °C. Vacuum and dry inert gases are most suitable as heat treatment atmospheres. The duration of the heat treatment may depend on the equipment, the process and the experience with the material. Lubricants should be completely removed prior to the heat treatment. If not, they may react with the Tantalum and cause embrittlement of the material.
Under atmospheric conditions Tantalum is covered by a stable, tight oxide layer. Although Tantalum is a reactive element this layer is the reason for the high corrosion resistance and the high biocompatibility. In its manufacturing process Vascotube® applies only appropriate tooling, lubricants and custom heat treatment equipment. Favorable to the manufacturing process is the excellent formability of the material.
We manufacture the Tantalum tubing according to ASTM F 560.
