Product Overview
Our Spherical Nickel-Titanium (Ni-Ti) Alloy Powder is a
high-performance shape memory alloy (SMA) material designed for
additive manufacturing (3D printing) applications. Produced via
plasma atomization (PA) or gas atomization (GA), this powder
exhibits excellent sphericity, uniform particle size distribution,
and superior flowability, making it ideal for Selective Laser
Melting (SLM), Electron Beam Melting (EBM), and Direct Energy
Deposition (DED) processes.
Ni-Ti alloy (Nitinol) is renowned for its unique shape memory
effect (SME) and superelasticity, making it invaluable in medical,
aerospace, robotics, and smart material applications.
Key Features
✔ High Purity (≥99.9%) – Low oxygen & carbon content for optimal
performance.
✔ Precise Composition Control – Adjustable Ni/Ti ratio (typically
50-55% Ni, 45-50% Ti).
✔ Excellent Sphericity & Flowability – Ensures smooth layer
deposition in 3D printing.
✔ Controlled Particle Size Distribution – Available in 15-45μm,
45-106μm, and 106-150μm.
✔ Superelasticity & Shape Memory Effect – Recovers original shape
upon heating.
✔ Biocompatibility – Suitable for medical implants and devices.
Applications
Ni-Ti alloy powder is widely used in industries requiring smart
materials, high fatigue resistance, and biocompatibility:
Medical: Stents, orthodontic wires, bone implants, surgical tools.
Aerospace: Actuators, deployable structures, vibration dampeners.
Robotics & Automotive: Micro-actuators, smart sensors, adaptive
components.
Consumer Electronics: Flexible connectors, micro-mechanical
devices.
Defense & Energy: Adaptive structures, thermal switches.
