TA2 Pure Titanium Wire Diameter 0.5mm-4mm Metal Wire Metalworking High Temp

Thinner diameters (0.5–1.0 mm) are ideal for jewelry wire-wrapping, fine binding, and delicate metalwork where flexibility is critical. Mid-range diameters (1.5–2.5 mm) suit general fabrication, lashing, and resistance welding filler. Thicker diameters (3.0–4.0 mm) are better for structural tie-wire, furnace fixtures, and load-bearing applications. When in doubt, start with a shorter length of your target diameter to test formability before committing to a full spool.

Yes — TA2 is the Chinese national standard (GB/T) designation that corresponds closely to ASTM Grade 2 commercially pure titanium. Both share similar chemical composition limits and mechanical properties, including good corrosion resistance and moderate strength. If your specification calls for ASTM Grade 2, TA2 is the functionally equivalent material.

Pure titanium wire can be used as filler in GTAW (TIG) welding of titanium base metals, but requires strict shielding gas coverage (argon back-purge and trailing shield) to prevent oxidation. Confirm the wire diameter matches your welding procedure specification. For critical structural welds, verify the wire meets your applicable AWS or AMS filler metal standard before use.

Titanium forms a self-healing titanium dioxide (TiO₂) passive layer that is highly resistant to chloride-induced pitting — a common failure mode for stainless steel in marine and chemical environments. In saltwater immersion, acidic solutions, and oxidizing media, titanium typically outperforms 304 and 316 stainless steel. For strongly reducing acids (e.g., concentrated hydrochloric acid), consult a materials engineer before specifying titanium.

For wire-wrapping pendants and small components, 5–10 meters of 0.5–1.0 mm wire is typically sufficient for multiple pieces. Bracelets and larger sculptural work may consume 15–25 meters per project. If you are new to titanium wire-wrapping, ordering a 5 m or 10 m length first lets you assess the wire's springback and work-hardening behavior before purchasing a larger spool.

Yes. Like most metals, TA2 titanium wire work-hardens as it is bent and formed, increasing stiffness and reducing ductility over repeated deformations. For intricate wire-wrapping, use smooth-jaw pliers to avoid surface scoring. Annealing (heating to approximately 650–800 °C in an inert atmosphere) can restore ductility if the wire becomes too stiff during complex forming operations.

Diameters up to 2.0 mm can typically be cut with quality flush-cut or diagonal wire cutters rated for hard wire. For 2.5–4.0 mm diameters, use heavy-duty cable cutters or an angle grinder with a thin cut-off disc for a clean edge. Avoid using standard scissors or low-grade cutters, as titanium's hardness will damage the cutting edges and produce a poor cut.
