Medical Implant Grade Metal Alloys

Austenitic Stainless Steels : Implant Grade

Click on the alloy details to view extended information. We have the following implant grade austenitic stainless steels available.

1.4472

Material No.

1.4472

X4CrNiMnMo21-9-4

ASTM

ISO 5832-9

ASTM F1586

1.4472 is an austenitic stainless steel with excellent corrosion resistance combined with good mechanical properties. Rigorous selection of the raw materials used in the steel and the use of consumable electrode remelting results in a very high quality grade making 1.4472 stainless steel a great choice for the production of permant surgical implants and osteosynthesis devices.

X4CrNiMoN23-21-1

ASTM

ASTM F2229

BioDur® 108 stainless steel alloy (a product of Cartech) is an essentially nickel-free austenitic stainless alloy with high nitrogen content to maintain its austenitic structure. BioDur® 108’s tensile and fatigue strength are superior to that of Type 316L (ASTM F138), 22Cr-13Ni-5Mn (ASTM F1314) and 734 alloy. Its pitting and crevice corrosion resistance is superior to Type 316L and equivalent to 22Cr-13Ni-5Mn and 734 alloy. Nonmagnetic and essentially free of ferrite phase.

Biodur® CCM

Material No.

CoCr28Mo

ASTM

ISO 5832-12

ASTM F1537

Alloy 1

Cobalt-Chrome-Molybdenum (CCM) is commonly used in the orthopaedic implant industry, due to its excellent biocompatibility and wear resistance. Biodur® CCM colbalt alloy has a much higher tolerance in the human body than that of Nickel or Cobalt and therefore less toxicity. This makes Biodur® CCM colbalt alloy ideal for implants for knee replacements, hip replacements, shoulder replacements and general fracture fixation.

MP35N® cobalt alloy is produced by vacuum induction melting (VIM) followed by vacuum arc remelting (VAR). MP35N® cobalt alloy is a multi-phase nickel-cobalt based alloy with a unique range of properties - ultra high strength, toughness, corrosion resistance, biocompatibility and it is also nonmagnetic. MP35N® cobalt alloy is used in a variety of medical applications including orthopaedic implants, lead wire for pacemakers and cardiovascular stents.

ASTM

ISO 5832-3

ASTM F136

6Al-4V ELI titanium alloy is widely used in the medical industry. Its excellent biocompatibility make it an ideal choice, especially when direct contact with bone or tissue is required. Titanium 6AL-4V ELI (Extra Low Interstitials) has improved ductility and fracture toughness compared to regular 6AL-4V.

ASTM F1295

6Al-7Nb titanium alloy is a dedicated, medium strength titanium alloy for surgical implants. The alloy was developed specifically for the manufacture of femoral component items used in hip prostheses. The metallurgy of 6Al-7Nb titanium alloy is closely analogous to that of Titanium 6AL-4V but biocompatibility is improved with the replacement of vanadium by niobium.
