Our production capability

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. MD Alloys has that expertise.

Powder production for medical implant alloys

Our alloy powders are manufactured in an inert gas atmosphere to ensure purity and the resulting spherical particle shape and reliable size ensure excellent layering and sintering.

We can offer a bespoke service, manufacturing alloys to customer specifications in terms of composition and particle size or we can offer:

Ingot production for medical implant alloys

We can produce ingots according to customer specific compositions usually in diameters ranging from 25mm to 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.

We favour the Electro Slag Re-melt (ESR) process for ingot production because it offers very high, consistent and predictable alloy quality. ESR optimises the alloy characteristics by reducing and eliminating defects in the metal structure. The resulting ingot is homogeneous and fully dense, without the central void or unsoundness that often results from other types of melting.
