Formula: Ta
Form: Tube
Material: Tantalum
CAS Number: 7440-25-7
Commodity: Metals
Purity:
99.9%
Tantalum tubes are utilized in environments requiring high resistance to corrosion, particularly in concentrated acids and high-temperature settings. They are commonly applied in chemical processing reactors, heat exchangers, and components for aerospace, where corrosion resistance and thermal stability are important. In medical applications, such as implants, tantalum’s biocompatibility and ability to withstand body fluids make it a preferred material. Furthermore, their application in research for materials science, semiconductor fabrication, and high-performance electronics benefits from their stability in extreme conditions, such as those found in etching chambers, vacuum systems, or advanced energy systems.
