Annealed Polished ASTM B365 99.95% Tantalum Rods
99.95% Annealed Polished Tantalum Bar
If you are looking for pure tantalum bar with excellent quality, then you need us. We make tantalum bars by ourselves-from powder right through to the finished products. As our input material, we use only the purest tantalum oxide, which will ensure that you benefit from a very high level of material purity.
Applications of 99.95% tantalum Bar
Tantalum is very hard and ductile, it can be draw into wire and foil. Tantralum is also featured 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.
