About implantable materials…

Titanium is particularly known for its excellent biocompatibility with the human body. Other materials stocked by ACNIS International, such as 316 LVM, a high nitrogen stainless steel, cobalt chrome, PEEK (exclusive to Brazil) and polyethylene, also known under the acronym UHMWPE, also exhibit biocompatible characteristics.

ACNIS International stocks and offers a large range of metal and plastic materials to orthopaedic implants (cups, femoral heads, knee prostheses, etc.) manufacturers, for the spine, for traumatology (screws, rods, pins, etc.) and for dental implants (manufactured from titanium and cobalt chrome bars and discs).

ACNIS International’s strength lies in its ability to supply raw material both for general or precision mechanics and also for world-renowned clients in the medical sector.

About non-implantable materials…

The majority of surgical and surgical tools are produced from stainless steels.

There are three main categories :

– Martensitic stainless steels: 420A, 420B, Cronidur 30, etc.

– Precipitation hardening martensitic stainless steels: 17-4 PH, Custom 455, etc.

– Austenitic stainless steels: 304L, 316L, 316Ti, etc.

These three categories of stainless steel meet the ASTM F899 standard, among others.

Plastic, in particular polyacetal copolymer, known by the name of POM C, is used for example for tool sleeves or as moulds for making implantable parts for the dental sector.

About 3D manufacturing of medical parts…

Additive manufacturing or 3D printing manufacturing is expanding rapidly. The number of machines for the production of metal parts is estimated at more than one thousand throughout the world and is likely to increase significantly in the coming years (Figures from 2017).

ACNIS International is interested in this sector and offers titanium and cobalt chrome powders.
