Why this matters
Selecting the wrong titanium grade introduces structural, compliance, and supply-chain risks that no downstream process can fix. Grade 5 (Ti-6Al-4V) covers roughly half of global titanium usage, but applying it outside its precise metallurgical window causes premature fatigue fracture, stress-corrosion cracking, or excessive thermal creep. The decision matrix — strength vs ductility vs fracture toughness vs biocompatibility vs cost — must be made before the print is released, not after the tooling is ordered. The articles below walk through the grades, the standards that govern them, and the trade-offs that matter in service.
