Spherical Nickel-Titanium Alloy Powder for Additive Manufacturing

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.
