GR1 titanium wire

GR1 Titanium Wire

LINHUI TITANIUM offers standard 10-meter (32.8-foot) lengths of precisely manufactured GR1 titanium wire with diameters as thin as 0.15mm (0.006" / AWG 34). Through regulated cold rolling technology, our wire achieves dimensional tolerance of ±0.01mm, guaranteeing constant formability for complex applications. This commercially pure titanium wire has an oxygen concentration of less than 0.18% and an iron level of less than 0.20%. Its excellent ductility—elongation usually surpasses 30%—eliminates springback problems during deep drawing or weaving processes. Since 2000, we have been a direct mill supplier, and we keep over 200 tons of stock on hand for quick shipping.

Strict chemical purity control and 100% NDT inspection are combined in our manufacturing process. To ensure there are no internal flaws, every spool is subjected to ultrasonic testing in accordance with AMS 2631 standards.

Key Features & Benefits

Superior Formability

The lowest yield strength among titanium grades (138 MPa minimum) enables maximum deformation without cracking. You can execute tight-radius bends and complex weaving patterns without intermediate annealing.

Corrosion Immunity

Stable TiO₂ oxide film resists seawater, wet chlorine, and organic acids. Ideal for marine hardware and chemical processing environments where stainless steel fails.

Lightweight Strength

Density of 4.51 g/cm³—45% lighter than steel—while maintaining higher strength-to-weight ratio than 316 stainless steel.

Specifications For GR1 titanium wire

Chemical Composition

Mechanical Properties

Manufacturing Process

Ingot Preparation

Vacuum arc remelting (VAR) eliminates impurities. Double-melt cycles ensure homogeneous chemistry throughout the billet.

Hot Forging & Extrusion

Billets undergo multi-pass reduction at controlled temperatures. This refines grain structure to ASTM E112 Grade 7 or finer.

Cold Drawing

Progressive die reduction achieves final diameter. Intermediate stress-relief annealing prevents work hardening. Our proprietary lubrication system maintains surface finish.

Final Heat Treatment

Bright annealing in protective atmosphere restores ductility. Rapid cooling preserves alpha-phase microstructure for maximum elongation.

Quality Inspection

Dimensional Verification

Laser micrometers check diameter at 10mm intervals. Statistical process control ensures ±0.01mm consistency.

Ultrasonic Testing

100% inspection per AMS 2631 Class B detects inclusions >0.4mm. Automated systems reject non-conforming material before spooling.

Mechanical Testing

Tensile tests verify yield strength 138–310 MPa and elongation >24%. Bend tests confirm 1T radius capability without surface cracks.

Traceability

Each spool includes EN 10204 3.1 mill test certificate with heat number. LECO ONH analyzer data for oxygen/nitrogen/hydrogen provided upon request.

Applications

Medical Devices

Surgical wire, orthodontic springs, and catheter guide wires benefit from biocompatibility and non-magnetic properties.

Marine Engineering

Rigging cables, fishing line leaders, and corrosion-resistant fasteners for subsea equipment.

Chemical Processing

Electrode wires for electroplating, filter meshes for aggressive media, and heating coils in corrosive environments.

Aerospace Components

Safety wire, locking mechanisms, and lightweight structural reinforcements where weight reduction is critical.

FAQ

Q: Can you supply diameters smaller than 0.15mm?

A: Yes, we produce wire down to 0.08mm (AWG 40) for specialized applications. Minimum order quantity increases for ultra-fine sizes.

Q: What's the difference between bright annealed and pickled finish?

A: Bright annealed offers smoother surface (Ra 0.4μm) for medical use. Pickled finish removes oxide scale, suitable for welding applications.

Q: Do you provide sample spools?

A: Free 1-meter samples available for testing. Shipping costs covered by recipient for international deliveries.

Q: Can wire be supplied in straightened lengths?

A: Straightened and cut lengths available in 500mm–3000mm segments. Additional processing fee applies for orders under 100 pieces.

Q: How does GR1 compare to GR2 for corrosion resistance?

A: Both grades offer similar corrosion performance. GR1 provides slightly better formability due to lower oxygen content, ideal for cold working.
