Tantalum rods are usually for machined tantalum parts, tantalum screws, tantalum nuts, high-temperature furnace parts, tantalum cathode, etc. TRM provides various dimensions of tantalum rods, under ASTM B365 and ASTM F560 for Medical Applications. Higher purity 99.95% or even 99.99% is available on request.  Our tantalum material is from Non-Conflict Resource.

Application: Tantalum rod is used as a beam stop, or machined parts, or tantalum electrode, which is for the disinfection of swimming pool, water and waste water treatment, etc.

Thermostability 91%
Machinability 87%
Corrosion Resistance 90%
