Q: What is the difference between using aluminum compared to a titanium bolt for a medical fastener?
A: Medical grade titanium bolts – grade 5 – have an incredible strength to weight ratio. They are 60% denser than aluminum but more than twice as strong. This makes a titanium bolt excellent for a load-bearing artificial implant. A Titanium grade 5 screw is not only bio compatible but offers a rare trait called osseointegration where the body’s natural bone and tissue actually bond to it.
