Since basic research started in the 1950s, JMM has continued to design various titanium alloys, to create material characteristics and to develop and research heat treatment technology. We have striven to select new titanium alloys suitable for medical materials among this research and apply them to various orthopaedic implants. In 2002, our vanadium-free titanium alloy was standardized by JIS* as titanium alloy for medical use.

Relation
of elongation and tensile strength of titanium materials |
|
 |
|
| Ti- 15Mo-5Zr-3Al alloy and Ti-6Al-2Nb- 1Ta-0.8Mo alloy are both examples of vanadium-free titanium alloy mentioned above. These alloys have excellent biocompatibility, strength and heat resistance. |

strength of titanium alloy |
|
|
|
| The beta transformation point (1030°C) of Ti-6Al-2Nb-1Ta-0.8Mo alloy is so high that heat resistance is extremely high. The strength is sufficient after heating by plasma spray, diffusion annealing for reinforcement of porous layer and coating bioactive materials at 980°C ~ 1000°C. |
