Orthopedic Application Of Tantalum Metal

2024-01-05 18:00:06

Tantalum is a rare metal which has important applications in many technical fields. Tantalum bar manufacturers would like to introduce the application of tantalum in orthopedics:

tantalum in medical use

Tantalum, known as a biophilic metal, has the element symbol Ta and an atomic number of 73. Tantalum itself has high strength, corrosion resistance, excellent biological compatibility, and excellent biological inertia. It is regarded as an ideal bone implant material. It has been applied in the medical field for more than half a century, including blood vessel clamping manufacturing for skull defect repair of cardiac pacemaker, bone joint prosthesis and surgical suture, etc.


Tantalum products are based on the principle that the cellular structure of bone trabecular metal is very similar to bone structure and is closer to bone in physical and mechanical properties than any other prosthetic metal. This unique, highly porous, bony trabecular-like structure is very conducive to inducing bone formation, and can quickly and widely infiltrate soft tissues and firm corporate attachment. Tantalum metal products have very strong load-bearing strength and elastic modulus, so as to minimize the stress shielding under physiological load conditions.


Tantalum is a structured biomaterial that can support very complex prosthetic shapes without the need for a metal substrate. It can be applied to different types of bone and soft tissue.


Tantalum products are characterized by their superior biocompatibility, allowing them to be compatible with bone and soft tissue after implantation. Good physical and mechanical properties, high loading strength and low modulus of elasticity
