The softest of the commercially-pure titanium grades — pure enough that it bends and forms without cracking, biocompatible enough for medical implants, and the version of titanium that anodizes most readily into structurally-colored surfaces. The grade jewelers reach for when they want titanium they can actually shape rather than just machine.

Commercially pure titanium with O ≤0.18%, Fe ≤0.20% per ASTM B265. HCP α-phase structure at room temperature. Density 4.51 g/cm³. Liquidus 1668 °C. Vickers ~120 HV annealed — soft enough to deep-draw and hydroform. Anodizes electrolytically across 0–120 V to structurally-colored TiO₂ films covering the visible spectrum.

Sustainability

  • embodied carbon kg co2e per kg35
  • sourceEditorial estimate from ICE / Granta CES EduPack class databases — industry mean, with cradle-to-gate boundary unless otherwise noted. Embodied carbon for any specific product depends on supplier mix, recycled content, and energy grid; verify against a primary source before using these numbers in a sustainability claim.
