The Case for Titanium

Ti-6Al-4V — grade-5 titanium — is a difficult material. It work-hardens as you cut it, eats tooling, and costs eleven times the equivalent stainless billet. A rational accountant would veto it.

But hang stainless hardware on a harness for a decade of salt water and it tells its age: crevice corrosion at every weld shadow, magnetism where it counts against you near instruments, and mass — always mass.

Our titanium D-rings weigh a third of their stainless equivalents, carry the same 220 kg rating, and will outlive the diver. In fatigue testing they exceeded one million load cycles without measurable deformation.

Some decisions in engineering are trade-offs. This one, at the level we operate, is not.
