Tantalum, discovered by Ekeberg, a Swedish chemist in 1802, is a metal that is closely related to niobium. Tantalum works similarly to copper in forming operations. It can be cold-formed. It can be spun, drawn, and hydro-formed like copper.

Tantalum also provides good thermal conductivity that, combined with its corrosion resistance, has made it the ideal choice for heat exchangers for acid processing equipment.

Tantalum is almost completely immune to attack by acids and liquid metals. It equals glass in resistance to acids and it is impervious to liquid metals up to 1650°F.

Tantalum is widely used in electronic components, chemical equipments, missile technology, and nuclear reactors. The electronics industry consumes the majority of tantalum produced (approximately 60%) for capacitors. Other industries concerned with corrosion, especially the chemical processing industry, are accounting for an increasingly large percentage of the market.
