Tantalum Wire is a shiny, silvery colored metal which is heavy, dense, malleable and ductile when pure. It is found in small quantities in minerals (generally in conjunction with niobium), and is isolated by conversion to the oxide and then the fluoro-complex, K2TaF7, from which the pure metal is obtained by electrolysis. Tantalum is extremely corrosion resistant due to the formation of an oxide film and is also resistant to acid attack (with the exception of HF). It will react with fused alkalis and a variety of non-metals at elevated temperatures. Tantalum can be used as a replacement for platinum for laboratory apparatus which has to have good corrosion resistance, and the metal is also used within the chemical industry for similar reasons. The fluids in the human body do not react with the metal and, hence, it is used for surgical implants without rejection. Other applications include the use of tantalum carbide in cemented carbides which are used as cutting tools. The pure metal is used in the electronics industry in the manufacture of various types of electronic equipment (e.g. rectifiers, capacitors, lamp filaments, etc.). Tantalum is also used in vacuum systems as it has a high absorption rate for residual gases. It is also used as an alloying element with, for example, nickel and molybdenum, to produce alloys which have good corrosion resistance, strength, and ductility.

Applications:
  • Tantalum is also used to produce a variety of alloys that have high melting points, are strong and have good ductility.
  • Alloyed with other metals, it is also used in making carbide tools for metalworking equipment and in the production of super-alloys for jet engine components, chemical process equipment, nuclear reactors, and missile parts.
  • Due to the biocompatibility of tantalum, tantalum wire is widely used in the medical field.
  • It can be used as the main material for repairing joints and bones.
  • It can also be used as a suture clip and vascular stent in medical devices.
  • Tantalum rod is the raw material from which tantalum wire is made. It can also be used to produce tantalum crucible, which is mainly used in high-temperature furnace, which is used in crystal, rare earth and metallurgical industry.
