The CAS Number for tantalum wire is 7440-25-7.
Tantalum wire has excellent corrosion resistance, especially in strong acids, hydrofluoric acid, sulfuric acid and other media. Tantalum has a density of 16.6 g/cm3, a melting point of about 2996°C, and a high mechanical strength and hardness.The electrical conductivity of tantalum wire is better and the coefficient of thermal expansion is lower.
Its chemical stability enables it to maintain good performance in high temperature, strong acid-base environment, and is widely used in chemistry, electronics, medical and other fields.
Tantalum alloy wire is another tantalum wire that is made of pure tantalum mixed with some elements and has special chemical properties.

Tantalum wire is widely used to manufacture the internal electrodes of tantalum capacitors, especially in applications with high capacity, high stability and high reliability requirements. Tantalum capacitors are often used in aerospace, medical equipment, high-frequency electronic equipment and other fields. Tantalum wire and tantalum alloys wire can be used machines as chlorinator springs. Tantalum capacitor lead wire are also made of high purity tantalum wire. In the 3D printing industry, Directed Energy Deposition (DED) and Electron Beam Additive Manufacturing (EBAM) both can utilize tantalum wire as a feedstock material. Tantalum wire is used in the aerospace field for high temperature components, such as jet engine components, rocket engines, etc., mainly using tantalum's high melting point (about 2996°C) and good high temperature resistance. Ta wire is a biocompatible material that does not cause toxic reactions to humans. Therefore, tantalum wire is used in some high-end medical devices, such as surgical instruments, artificial joints, bone repair equipment and so on. Tantalum spring made of tantalum wire is mainly used in high temperature, high corrosion, strong radiation and other special environments. The high strength, corrosion resistance and high temperature resistance of tantalum spring wire make tantalum spring wire irreplaceable in these fields. Tantalum can also be made into tantalum alloy wire. Tantalum wire also can be used to machined as tantalum necklace and tantalum earrings. Short tantalum wire pellets are used as an evaporation medium. They are employed in semiconductor, magnetic storage devices, optical coatings, and corrosion-resistant coatings.
In addition to Tantalum Wire, we also produce Tantalum Tube & Pipe, Tantalum Sheet & Plate, Tantalum Ingot, Tantalum Pellets, Tantalum Foil, Tantalum Rod&Bar，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.
