Titanium Jewelry

Key Terminology Notes for Accuracy: Ti-6Al-4V ELI: The "ELI" (Extra Low Interstitial) suffix is retained to emphasize the ultra-pure variant of the Ti-6Al-4V alloy, critical for medical/body-piercing use. "Titanium steel": Placed in quotes with a clarifying note ("not a titanium-based metal") to correct the common commercial misnomer, as 316L stainless steel contains no titanium. ASTM/ISO Standards: Full standard designations (e.g., ASTM F136, ISO 10993) are preserved to maintain technical rigor, as these are globally recognized in materials science. "Biocompatibility": Distinguished from "low nickel release" to highlight the regulatory certification gap—titanium jewelry meets medical-grade biocompatibility, while 316L stainless steel only minimizes nickel-related irritation.
