This titanium round wire is drawn from TA2 commercially pure titanium (≥99.5% Ti), giving you a material that resists corrosion, stays dimensionally stable, and keeps its silver-grey finish without plating or coating.\u003c\/p\u003e\n\u003cp\u003eEach spool is a single continuous length of round-profile titanium wire. Diameters range from Ø0.5 mm (≈0.020 in) to Ø4.0 mm (≈0.157 in), and available lengths run from 1 m up to 100 m per order — letting you match the quantity to your project without waste. The wire ships on a coil or spool depending on length selected.\u003c\/p\u003e\n\u003cp\u003eTypical applications include titanium wire for jewelry making and wire-wrapping, structural armature wire for sculpture and model-making, resistance-heating elements in DIY kiln and annealing setups, and lightweight lashing or binding wire in aerospace-adjacent hobby builds where weight and corrosion resistance both matter.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e TA2 titanium is not weldable with standard MIG\/TIG consumables without inert-gas shielding.

Ø2.5 mm and above are better suited to heavier sculptural or industrial applications.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow strong is TA2 titanium wire compared to stainless steel wire?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eIn 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.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWill this wire corrode or tarnish over time?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eTitanium 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.

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.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eIs this wire suitable for use in body jewelry or skin-contact applications?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eTA2 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.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow do I cut and work-harden this wire?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eTitanium 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.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat length should I order for a specific project?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eFor wire-wrapping a single pendant, 1–3 m of Ø0.5–1.0 mm wire is typically sufficient.
