The CAS Number of tantalum strip is 7440-25-7.
The main component of tantalum foil is tantalum, and the purity of tantalum foil is usually higher than 99.95%.
The density of tantalum strip is about 16.6 g/cm3. Tantalum strip has a melting point of up to 2996°C.
Ta foil has good strength and ductility.
In terms of chemical properties, tantalum foil has excellent corrosion resistance to acids, alkalis and chlorides. However, the stability of tantalum strip in hydrofluoric acid is fragile. Ta strip can form a dense oxide film in the air, which enhances the corrosion resistance and stability of tantalum foil. These characteristics make tantalum foil perform well in high temperature and corrosive environments.

Tantalum foils are mainly used in the manufacture of high-performance solid-state capacitors, especially in mobile phones, computers and other consumer electronics. Tantalum strips are also used in high-frequency circuits and high-temperature electrical components. Ta strip is widely used in chemical reactors, storage tanks and pipelines because of its excellent corrosion resistance.
In the medical industry, tantalum foils are also commonly used to manufacture biocompatible implants and medical devices, such as heart stents and orthopedic implants. Ta alloys foils are also used in the manufacture of superalloys and thermal protection materials, suitable for the high-temperature environment of aircraft and spacecraft.
In addition to Tantalum Foil and Strip, we also produce Tantalum Tube & Pipe, Tantalum Sheet & Plate, Tantalum Ingot, Tantalum Pellets, 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.
