Tantal

UNS R05200

Tantalum is a tough, ductile, brilliant gray metal. Tantalum and Tantalum alloys (Ta2.5W or Ta10W) are used in electronic components, chemical processing, medical industry, aerospace, superconductivity industry and a lot of other applications. The advantages of tantalum are in an excellent corrosion resistance, high temperature strength, good machinability and bio-compatibility.
