We stock and sell Biodur 108 in rod form.
BioDur 108 is a tough, non-magnetic material frequently used for medical purposes. BioDur 108 is hardened through cold working, a process in which metal is shaped while at its ambient temperature. This metal is nearly nickel free, cobalt free, and FDA approved for implantable medical devices. BioDur 108’s non-magnetic composition makes it MRI friendly, and its low nickel status makes it safer for metal sensitive individuals than other stainless steels. A few of BioDur 108’s medical uses include:
- Bone plates
- Bone screws
- Hip and knee parts
- Orthodontic appliances
- High strength surgical instruments
BioDur 108’s high nitrogen and low nickel content gives it improved fatigue strength in comparison to nickel-containing alloys. It is a metal great for metal sensitive individuals and large-scale production alike.
