Titanium Wire Highly Pure Diameter 0.5mm - 5mm Ti TA2 Metal Wires Various Length

For delicate wire-wrapping around beads and cabochons, Ø0.5 mm and Ø1.0 mm are the most commonly used sizes — they bend easily by hand and hold intricate loops without springback issues. For structural frame elements within a piece (e.g., a ring shank or pendant bail), Ø1.5 mm to Ø2.0 mm provides enough rigidity to hold shape after forming. Ø2.5 mm and above are better suited to heavier sculptural or industrial applications.

In the annealed condition, TA2 titanium wire has a tensile strength of approximately 240–345 MPa, which is broadly comparable to 304 stainless steel in the annealed state (typically 515 MPa UTS, but with much higher density). Titanium's advantage is its strength-to-weight ratio: it delivers similar structural performance at roughly 40% less mass. For applications where absolute tensile load matters more than weight, stainless steel may be preferable; for weight-sensitive or corrosion-critical uses, titanium is the better choice.

Titanium forms a stable, self-repairing titanium dioxide (TiO₂) oxide layer on its surface that prevents further oxidation. In normal atmospheric conditions, saltwater, and mild acidic environments, the wire will not rust, pit, or tarnish. The natural silver-grey color is stable long-term without any protective coating. For highly concentrated acids (e.g., hydrofluoric acid) or strong oxidizing environments, consult material compatibility data before use.

Yes. Because the wire is bare, uncoated TA2 titanium, it is fully compatible with anodizing. Titanium anodizing is a voltage-controlled process that thickens the oxide layer to produce interference colors ranging from gold and purple at lower voltages to blue and green at higher voltages. No dyes are involved — the color is structural. Standard titanium anodizing equipment and electrolyte solutions (e.g., dilute TSP or ammonium sulfate) work with this wire.

TA2 commercially pure titanium is widely used in body jewelry and medical implant contexts due to its biocompatibility and hypoallergenic properties. The wire contains no nickel, which is the most common cause of metal contact allergies. However, for implant-grade body jewelry, ASTM F136 (Ti-6Al-4V ELI) or ASTM F67 (CP Ti) certification is typically required — this wire is not certified to those standards. For external skin-contact craft applications (e.g., wire-wrapped rings worn on the finger), it is generally considered safe for most users.

Titanium wire can be cut cleanly with flush-cut wire cutters or a rotary tool with a cutting disc. Standard jeweler's flush cutters handle diameters up to Ø1.5 mm comfortably; for Ø2.0 mm and above, use heavy-duty cutters or a disc. Like all annealed metals, repeated bending will work-harden the wire, increasing stiffness and reducing ductility over time. If the wire becomes too stiff to form, it can be re-annealed by heating to approximately 700–800 °C in an inert atmosphere or with adequate torch coverage, then allowing it to air-cool.

For wire-wrapping a single pendant, 1–3 m of Ø0.5–1.0 mm wire is typically sufficient. A full wire-wrapped ring uses roughly 0.5–1.5 m depending on complexity. For coil-winding or armature work, estimate your total coil circumference multiplied by the number of turns, then add 15–20% for waste and joins. Longer length options (20 m, 50 m, 100 m) offer a lower per-meter cost and are recommended if you work with titanium wire regularly or in production quantities.
