Tantalum (Ta)
Ta 99.95%+
A highly corrosion-resistant refractory metal with exceptional biocompatibility. The material of choice for aggressive chemical environments and medical implant applications.
Material Properties
Tantalum is renowned for its exceptional corrosion resistance, surpassing that of platinum and gold in many environments. Its oxide layer provides self-healing protection, making it virtually immune to attack by most acids. Combined with excellent biocompatibility, tantalum is indispensable in chemical processing and medical applications.
Applications
- Chemical processing equipment
- Heat exchangers for corrosive media
- Tantalum capacitors (electronics)
- Medical implants and devices
- Surgical instruments
- Laboratory equipment
- Sputtering targets
- Spinnerets for fiber production
- Vacuum furnace components
- Corrosion-resistant fasteners
