Tantalum

TANTALUM :- Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant conforming to R05200 , R05400 , R05255 , R05240 , R05252 ETC 

Tantalum is a ductile metal. Tantalum has excellent corrosion resistance to most chemicals except hydrofluoric acid. Tantalum has a melting point exceeded only by tungsten & rhenium. The melting point of tantalum is approximately 3017 degrees Celsius. Tantalum’s main end uses are in capacitors, vacuum furnaces, chemical process equipment, nuclear reactors and aircraft parts.
