TC4 Highly Pure Titanium Wire Diameter 1mm 2mm 3mm Metal Wire Metalworking

TC4 is the Chinese designation for the Ti-6Al-4V alloy — a titanium alloy containing approximately 6% aluminum and 4% vanadium. Compared to commercially pure (CP) titanium, TC4 offers roughly 30–50% higher tensile strength while remaining lightweight and corrosion-resistant. If you need a wire that holds its shape under load or spring-back tension, TC4 is the better choice over CP grades.

For ear wires, fine coiling, and delicate chain-style work, the 1.0 mm diameter is the most versatile starting point. The 2.0 mm wire suits heavier bangles, cuff frames, and wrapped-stone settings. The 3.0 mm wire is better suited to rigid structural elements like ring shanks or sculptural armatures rather than fine jewelry detail work.

Yes. TC4 titanium wire can be cut cleanly with flush-cut or standard wire cutters for the 1.0 mm and 2.0 mm diameters. For the 3.0 mm diameter, heavy-duty wire cutters or a rotary tool with a cutting disc will give a cleaner result and reduce tool wear. Avoid using scissors or craft knives.

TC4 titanium is widely regarded as biocompatible and is used in medical implants and body jewelry. It does not contain nickel, making it a practical option for people with metal sensitivities. However, individual reactions vary — if you have known metal allergies, consult a dermatologist before extended skin contact.

Titanium forms a stable, self-repairing oxide layer that resists saltwater, humidity, and mild acidic environments far better than steel or aluminum wire. It is a common choice for marine rigging, outdoor sculpture, and coastal installations. For highly concentrated acid environments, verify chemical compatibility before use.

TC4 titanium can be TIG welded using argon or argon/helium shielding gas to prevent oxidation. It cannot be soldered with standard silver or lead-based solders — titanium does not wet with conventional flux-based solders. For jewelry joining without welding, cold-connection techniques (riveting, wire-wrapping, tube-setting) are the practical alternatives.

For single jewelry pieces or prototyping, 1 m or 2 m is usually sufficient. For batch production of multiple items or larger fabrication projects, the 5 m or 10 m options offer a lower per-metre cost. The wire is supplied as a straight or loosely coiled length — not on a spool — so factor in storage when ordering longer cuts.
