Spherical Tantalum Powder

Product	Spherical Tantalum Powder (Ta Powder)
Part Number	MEP73-2
CAS Number	7440-25-7
EINECS No.	231-135-5

Tantalum has excellent biocompatibility. The tantalum implant formed by 3D printing has the closest elastic modulus to human cartilage tissue, so it is the most ideal orthopedic implant material. Radio frequency plasma spheroidized tantalum powder is widely used in biomedical field because of its high sphericity, good fluidity, high purity, high bulk density, full density, and no hollow powder.

TRM provides Spherical Tantalum Powder, Nano Tantalum powder, and Micro Tantalum Powder. Please contact us for more details.
