Orthopaedic Implant Alloys

Bars For Orthopaedic Implants

Our production capabilities include Vacuum Induction Melting (VIM), Vacuum Arc Re-melting (VAR) and Electroslag Re-melt (ESR). We can produce ingots according to customer specific compositions usually in diameters ranging from 25mm – 200mm. Our customers normally require ingots according to ISO 5832-4.

We can also manufacture wrought material (typically ISO 5832-12) by subcontracting ingot forging to our partners in Sheffield, UK.

Cobalt chrome molybdenum (CCM) alloys are recognised by the International Standards Organisation (ISO) and the American Society of Testing and Materials (ASTM) as materials suitable for medical implants. In fact, hundreds of tons of CCM are used every year by the World’s leading manufacturers of orthopaedic implants for the manufacture of hip, knee and spinal implants.

 CCM is biocompatible and integrates with bone (osseointegration). It is very strong and extremely resistant to wear. Of course not all CCM alloy is the same. Before the alloy is turned into a medical implant by casting, forging, machining or powder processing, it needs to be expertly manufactured.

 Our raw materials are supplied by Norilsk in their elemental form. All of our alloys are produced in our metallurgy mill.  We are responsible for mixing the elemental constituents to create our alloys. Our state of the art furnaces ensure a homogenous melt resulting in alloys with optimal composition and mechanical properties.
