Nitinol Wire

Key Advantages

SE or SME options: choose constant-force superelastic wire, or shape-set wire for triggered actuation.
Tight Af / R-phase control for consistent performance across heats and lots.
Fine diameters and tight tolerances enable compact mechanisms and orthodontic components.
Clean, oxide-controlled surfaces support bonding, coating and joining processes.
Flexible supply: coils/spools or straight cut lengths; small-batch prototyping available.

Primary Applications

Orthodontic & guide systems (arches, springs, torque elements).
Mini-actuators & robotics (thermal triggers, compact motion).
Fixtures & clamps (constant-force holding, vibration tolerance).
Research & prototyping (function-testing of SE/SME elements).

Testing & Inspection (typical on request)

Transformation temperature testing (DSC or bend-and-free recovery).
Tensile and cyclic fatigue sampling by size/condition.
Surface/defect inspection; eddy-current continuity checks (size-dependent).
Chemical analysis (Ni content, low interstitials).
Dimensional checks: OD, ovality, straightness/coil uniformity.

Product Description

LuminaTitan supplies precision nitinol (nickel-titanium, NiTi) wire engineered for repeatable superelastic (SE) and shape-memory (SME) behavior. Produced under controlled thermo-mechanical processing and inspected in-house, our NiTi wire delivers consistent transformation temperatures, stable cyclic response and corrosion resistance for medical R&D and high-precision industrial applications.

*Regulatory compliance and final device approvals remain the responsibility.

Packaging & Delivery

Packaging: vacuum/moisture-barrier wrap on spools or straight bundles; export plywood cases.
Labeling: alloy, diameter, condition, Af target (if applicable), heat/lot, coil weight/length, PO.
