Advanced Metal Sheet Solutions with Shape Memory Performance
The nitinol metal sheet combines strength, flexibility, and thermal response. Made from a nickel-titanium alloy, this smart material supports innovation across medical, aerospace, and industrial sectors. It’s valued for both shape memory behavior and high fatigue resistance.
Precision Alloy Engineering
Engineered with a 55.8% Nickel and 44.2% Titanium composition (±0.15%), the sheet offers exceptional consistency. Purity reaches 99.995%, minimizing intermetallic formation. Additionally, each batch comes with traceable certification, including ISO 13485 and AS9100. Austenite finish temperatures are fully customizable from –20°C to +110°C.
Custom Surface Finishes
To suit different industry needs, we offer four types of surface finishes:
| Finish Type | Ra (μm) | Highlights | Used For |
|---|---|---|---|
| Mirror Electropolish | ≤ 0.05 | Particle-free, ultra-smooth | Implants, microscopy parts |
| Micro-blasted Matte | 0.8–1.2 | Enhances coating adhesion | Aerospace hardware |
| Thermal Oxide | 1.5–2.0 | Adds wear resistance (HV 650+) | Industrial forming dies |
| Passivated | 0.3–0.5 | Bioprocess-ready, ASTM F86-compliant | Surgical and lab instruments |
These finish options help boost the sheet’s performance in real-world conditions.
Versatile Dimensions and Tight Tolerances
Available in thicknesses ranging from 0.05 mm to 15 mm, the sheets serve both lightweight and structural needs. Tolerances remain tight—within ±0.5% for thin formats and ±1% for thicker ones. For complex designs, we support photochemical etching, micro-perforation, and laser cutting with 50 μm kerf width.
Reliable Testing and Fatigue Resistance
Each sheet undergoes detailed performance testing, including:
Recoverable strain up to 300% (ASTM F2516)
10⁷-cycle fatigue life at 3% strain
Consistent transformation temperature (±1.5°C)
These tests ensure that the product performs under pressure and across thermal cycles.
Medical and Aerospace Application Versatility
In the medical field, nitinol supports advanced functionality. Examples include:
MRI-compatible stents
Orthodontic components delivering precise force
Flexible surgical instruments lasting through high cycle loads
For aerospace engineers, the material aids in:
Cryogenic actuators working at –196°C
Vibration mounts absorbing up to 90% energy
Thermal-coupled assemblies in fuel systems
Production Quality and Technical Support
We use a VIM/VAR triple-melt process that limits inclusions to less than 10 ppm. Each batch is:
Verified by EDX analysis
Scanned for 3D surface mapping
Examined for transformation hysteresis
Subjected to strain-based fatigue validation
Compliance includes RoHS, REACH, and FDA 510(k) standards. Cleanroom handling ensures product integrity during packing and delivery.
Fast Turnaround and Support Services
Time-sensitive projects benefit from:
48-hour prototyping for samples under 500g
98% same-day shipping for stocked items
Metallurgist support with average response time under 2 hours
These services help teams stay ahead on development timelines.
