Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The metal is renowned for its resistance to corrosion by acids. Tantalum is estimated to make up about 1 ppm or 2 ppm of the Earth’s crust by weight. Tantalum has found wide use in the making of surgical appliances. It can replace bone, for example in skull plates; as foil or wire it connects torn nerves; as woven gauze it binds abdominal muscle. Tantalum has also been used to make a variety of alloys.
