Tantalum Balls offered by Goodfellow, are available in 4 variations. Tantalum is known for its corrosion resistance and bio-compatibility. Tantalum Balls are commonly used in prosthetics due to tantalum's ability to osseointegrate with bone. They are also utilized in chemical processing equipment because of tantalum's immunity to practically all organic and inorganic chemicals at room temperature.
