Tantalum Wire
Tantalum Wire
Tantalum wire is a ductile and corrosion-resistant metal wire made from tantalum, a rare and hard transition metal. Tantalum wire is used in a wide range of applications, including in the electronics industry, where it is used for wiring in capacitors, in the medical industry for implants and surgical tools, and in the aerospace industry for high-temperature applications. Tantalum wire is also used in the chemical industry for its resistance to corrosion and high melting point. Tantalum wire can be produced in different diameters and can be further processed into various shapes and forms, including coils and filaments.
