Applications of 99.95% Tantalum Bar
Tantalum is featured by hard and ductile, it can be draw into wire and foil. Tantralum is also characterised by small thermal expansivity and strong toughness. Tantalum also has excellent chemical properties and high corrosion resistance.
These features let tantalum has beeen widely applied in chemical, electronic and electrical industries.
Tantalum can also play an important role in modern medicine.
