Q: We are researching a bolt to be used in a medical implant? Is there a standard material you can suggest?
A: While there are a variety of possibilities depending on the requirements for the screw, a go to material for many implantable fasteners for good strength and biocompatibility, is Titanium Grade 5. It offers a fairly high tensile strength of 148ksi. It is also non-toxic and allows for osseointegration where bones and tissue can easily grow around it.
