Bio-Medical Grade Materials Information Center

Bio-medical grade metals and alloys are used in a variety of applications in the medical field, most commonly; they are used for implant and instrumentation
applications. Research in the orthopedic biomaterials field has increased as the need for such materials has grown due to the aging patient demographics.

Implant alloys are typically derived from three materials systems: stainless steels, cobalt-chromium based alloys and titanium alloys.

Stainless steel was established into general engineering as a new corrosion-resistant material in the early 1900s and was employed in surgical applications soon after. Stainless steel used in medical applications is made out of several components: chromium, nickel and molybdenum. The chromium gives the metal its corrosion and scratch resistance. The nickel offers an even and polished finish. The molybdenum increases hardness and helps sustain a cutting edge.

Cobalt-chromium based alloys or ceramic materials (aluminum oxide or zirconium oxide) are used in making orthopedic implants. These materials are biocompatible, resistant to corrosion, degradation, and wear, and they have mechanical properties that duplicate the structures they are intended to replace.

Titanium has become a fundamental material used in medicine due to its ability to resist corrosion, its biocompatibility and its natural ability to join with human bone. There are many medical materials made with Titanium including, surgical titanium instruments, orthopedic titanium rods, pins and plates, medical and dental titanium. Titanium CP (Commercially Pure) is offered in four types: CP-1 GR 4, CP-2 GR 3, CP-3 GR 2, and CP-4 GR1.
