Description Of Tantalum Wire 99.95% ASTM B365
Tantalum Wire 99.95% is a high-purity tantalum metal wire manufactured from pure tantalum (UNS R05200) to ASTM B365 standard. Tantalum is a silver-grey refractory metal with a melting point of 2996°C, excellent corrosion resistance, and superior biocompatibility. These wires are widely used in tantalum capacitors, chemical processing equipment, medical implants, and vacuum coating applications.
Tantalum offers a unique combination of properties that make it ideal for demanding applications. With a melting point of 2996°C (the fourth-highest among all metals, after tungsten, rhenium, and osmium), tantalum wire can withstand extreme temperatures. The material also offers outstanding corrosion resistance to acids, alkalis, and most chemical media, and it is biocompatible, making it suitable for medical implant applications.
99.95% pure tantalum wires are available in custom diameters and lengths, with surface finishes including bright, pickled, polished, and annealed. Typical applications include tantalum capacitors, corrosion-resistant equipment, medical implants, and vacuum coating evaporation sources.
