Tantalum Rod (Tantalum Bar) is well-known mainly for its unmatched corrosion resistance and chemical inertness. Tantalum Rod (Tantalum Bar) is also extremely stable at high temperatures, since tantalum has a melting point around 3000°C. Tantalum is also one of the most bio-compatible metals available and is also radio-opaque due to its high density (16.68 g/cm3).
