Thin Titanium Wire

Non-contact laser micrometers are the standard for in-process and final inspection. They project a laser beam across the wire; the shadow cast is measured to calculate diameter with sub-micron resolution. For the finest wires (<0.05mm), scanning electron microscopy (SEM) may be used for verification. Suppliers provide certified test reports with actual diameter measurements.

Welding is possible but challenging due to the small mass. Laser micro-welding and resistance welding are the primary methods. Soldering titanium is difficult because of its stable oxide layer. It requires active fluxes (often containing fluoride) or specialized techniques like ultrasonic soldering. For electrical connections, crimping or wire bonding is often preferred over soldering.

Breakage is usually due to: 1) Microscopic surface defects (scratches, inclusions) acting as stress concentrators. 2) Excessive work hardening without adequate intermediate annealing. 3) Improper tension during spooling causing yield or fatigue. 4) Kinks or sharp bends introduced during handling. Using wire from a reputable source with controlled processes minimizes these risks.

Yes, MOQs are typically high due to the specialized setup and long run times required for fine drawing. A single drawing run may produce tens of kilometers of wire. MOQs can range from a few kilograms to a full spool (which may contain many kilometers). For prototype or R&D needs, inquire about purchasing from existing stock or remnant spools.

Thin wire is typically much stronger in terms of tensile strength due to extensive cold work from drawing. A 0.1mm diameter Grade 2 wire may have an ultimate tensile strength exceeding 1000 MPa, compared to 345 MPa for annealed sheet. However, this comes with significantly reduced ductility. The wire is strong but brittle if bent sharply.
