TA0021 Tantalum-niobium wire (Ta-Nb wire)

Tantalum-Niobium Wire Description

Tantalum-Niobium wire has a melting point exceeding 3 000°C and maintains its structure and properties at temperatures up to extreme levels. It is used in the manufacture of components that operate under high-temperature conditions, for example in engine parts and rocket nozzles in aerospace. The wire exhibits resistance against a variety of chemicals and corrosive media; consequently, it delivers stable performance in chemically aggressive environments, including marine engineering and chemical processing facilities. It shows high mechanical strength, hardness and tensile strength. Its electrical and thermal conductivity permit its use as connecting wire for electronic components, as electrode material and as a heating element for high-temperature furnaces. It also meets biocompatibility requirements for applications in medical devices such as surgical suture material and orthopaedic implants.
