Tantalum Tube & Pipe of us meets the standard ASTM B 521 R05400 and ASTM B 521 R05200.
The CAS Number for tantalum tube is 7440-25-7.
Tantalum tube has excellent physical and chemical properties.The density of tantalum seamless pipe is about 16.6 g/cm3, the melting point of tantalum tubing is as high as 2996°C, and it has excellent high temperature resistance. Tantalum seamless piping are chemically stable and have good corrosion resistance to most acids (except fluoric acid) and alkalis.
Tantalum tubes are suitable for chemical reaction vessels and medical devices. Tantalum also has high electrical and thermal conductivity, making it widely used in electronics and aerospace.
In addition, tantalum seamless tubes perform well in terms of biocompatibility and are suitable for use in implants.

Tantalum tubes play an important role in coating technology and are mainly used as targets in vacuum coating equipment. The high melting point and excellent electrical conductivity of tantalum tubes enable them to work stably in high temperature environments. Tantalum tubes are suitable for physical vapor deposition (PVD) processes. In this process, the tantalum tube target is heated to high temperatures and evaporated or sputtered to form tantalum film, which is widely used in the surface coating of semiconductors, optical devices and hard disks. Tantalum alloys tubes are commonly used in the manufacture of engine components, fuel systems and thermal barrier materials that maintain stable performance in extreme environments. In addition, the light weight and strength of tantalum welded tubes make them ideal structural materials to help reduce the weight of aircraft and improve fuel efficiency. Tantalum pipe is also widely used in spacecraft electronic equipment because of its excellent electrical conductivity and anti-radiation ability. Tantalum seamless pipe also can be used to machined as tantalum ring.
In addition to Tantalum Tube and Pipe , we also produce Tantalum Sheet & Plate, Tantalum Ingot, Tantalum Pellets, Tantalum Strip, Tantalum Rod, Tantalum Wire, Tantalum Disc, Tantalum Shield, Tantalum Target, Tantalum machined parts, Tantalum Spherical Powder. They meet Standard ASTM B 364, ASTM B 365, ASTM B 708, ASTM B 521, ASTM F560 R05200, R05400.
