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.
Principled BSDF defaults derived from the sphere iridescent finish. Reasonable seed for Blender, Substance, Keyshot, Rhino — tune per material. Or grab the whole library at once: ForMaterials library →

House vocabulary — terms ForMatter uses with intent.
Materials and processes for people who design and make things.
A local-first library of materials, processes, applications, and finishes — equal weight, citable everywhere, so a student can move from "what is this" toward "what's actually buildable here, now, by me." Part of the renato.design ecosystem — sibling of Plenum, Specimen, Ingenue, gesture, graf, and the Renato Rhino plug-ins. Form and matter, inseparable.
Half of teaching materials is teaching how the material is made into the thing. The standard subscription library was always light on that half. The wedge here isn't better samples or a prettier interface — it's treating Process as a peer entity, not a footnote.
