Tantalum Ta Plate Sheet Foil Strip Rod Wire Tube Target

Tantalum is a grayish silver, dense, ductile, very hard, easily fabricated, and highly corrosion resistant metal. It is part of the refractory metals group and occurs naturally in the mineral tantalite, always together with the chemically similar niobium.

Tantalum is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulphur trioxide. The element has a melting point exceeded only by tungsten and rhenium.
