Tantalum Capillary

Tantalum capillary tube is a high-quality material with many excellent properties. It has a high melting point and high hardness, making it stable at very high temperatures and pressures, and has a low coefficient of thermal expansion, ensuring dimensional stability. Tantalum capillary tubing also has excellent corrosion resistance and good electrical properties, making it excellent in a variety of chemical and industrial applications. In addition, the biocompatibility of tantalum capillaries makes them widely used in medical implants and other biomedical applications. These properties make tantalum capillary tubes ideal for use in aerospace, electronics, petrochemical, and medical applications, and we are committed to providing the highest quality tantalum capillary tubes to meet the needs of a variety of applications.

Tantalum and niobium coexist, and their hardness is second only to tungsten, rhenium, and osmium among metal elements. It is easily hydrogenated, but it is the most corrosion-resistant metal and has a very good affinity with human tissue. Commonly used in the manufacture of medical equipment and special instruments. Because its special manufacturing process is quite different from other metal capillary tubes, there are very few manufacturers that produce tantalum capillary tubes.

Specifications of our ultra-fine tantalum capillary tubes:
Material: Tantalum, 99.95%
Size: outer diameter Φ0.2~Φ8mm, wall thickness: T0.015~0.5mm.
Highest accuracy: outer diameter: Φ±0.003mm, wall thickness: T±0.005mm, length: L±0.03mm.
Appearance: Observed under a microscope, the inner and outer surfaces of the pipe show uniform metallic luster, without oxidation, hydrogenation, discoloration, scratches, deformation, burrs, etc.
Specifications can be customized based on user requirements based on the above range.

As a traditional high-quality marking tape (development marker), tantalum imaging rings have been widely used in the medical industry, such as various minimally invasive surgeries such as cardiac surgery. The actual imaging effect is close to the traditional iridium-platinum imaging ring.
The outer diameter of the developing ring is 0.2mm to 8.0mm, and the wall thickness can be as thin as 0.02mm.
