Do you think Grade IV cold titanium is titanium alloy? Or pure titanium? Many people are always confused about this problem. in fact, Grade IV cold working titanium is one of the pure titanium classifications, but it is better than Grade IV pure titanium, According to the small editor, the high-end Swedish Nobel implant uses four levels of cold titanium.

From the perspective of technology, the fourth stage cold working titanium is really pure titanium

The fourth stage cold working titanium is cold working based on the fourth stage pure titanium The biocompatibility of pure titanium can be retained after treatment, and it can also reach the mechanical strength of Grade V titanium, which is firm and not easy to break; Therefore, in terms of production process, the fourth stage cold titanium is still pure titanium.

However, the fourth stage cold working titanium is stronger than the fourth stage titanium:

For example, Jamey AC uses high strength Grade IV cold working titanium, and some Korean implants use Grade IV pure titanium; But their strength is the difference between 689 and 483, and they are not the same grade implants.

Titanium alloy material is a metal based on titanium entering other elements. Therefore, in terms of combination, the purity of titanium in titanium alloy is far lower than that of pure titanium material, and there is still a big difference between the two.

Knowledge extension: classification of common implant materials

At present, titanium is the main implant, Titanium materials are divided into pure titanium, titanium alloy and titanium zirconium alloy.

Pure titanium is divided into Grade I to Grade V or even Grade VI now. The higher the titanium content in the material, the more stable the material is, and the more conducive to the stability of the implant.

We roughly divide pure titanium materials into Level 1<Level 2<Level 3<Level 4<Level 4 cold working<Level 5<Level 6.

At present, most of the implants use implants above Grade IV pure titanium. For example, the representative implants of Nobel in Sweden mostly use four stage cold titanium.
