How to Choose the Right NiTi50 Powder

Choosing the right NiTi50 powder depends on factors such as particle size distribution, atomization process, and specific application requirements.

1. Particle Size Distribution (PSD)

• Fine powders (15-45µm) → Best for LPBF (Laser Powder Bed Fusion)
• Medium powders (45-105µm) → Suitable for EBM & Binder Jetting
• Coarse powders (50-150µm) → Used in DED (Direct Energy Deposition)

2. Powder Morphology

• Spherical Powder → Best for 3D printing and powder bed fusion technologies
• Irregular Powder → Suitable for Binder Jetting & Sintering

3. Atomization Process

• Gas-Atomized Powder → High purity, excellent flowability, best for 3D printing
• Plasma-Atomized Powder → Ultra-high purity, best for medical and aerospace applications

Production Methods

The production method of NiTi50 powder plays a crucial role in determining its particle shape, purity, flowability, and overall performance. Given the stringent requirements for medical, aerospace, and high-tech applications, selecting the right production technique is critical.

Comparison of Production Methods

1. Gas Atomization (GA)

Process:

• NiTi50 alloy is melted and atomized using high-pressure inert gas (argon or nitrogen), rapidly cooling the droplets into fine, spherical particles.

Advantages:
✔ High sphericity, improving powder flowability and printability
✔ Low oxygen content, preventing oxidation defects
✔ Excellent particle uniformity, ensuring consistent layer deposition in AM

Best for: Laser Powder Bed Fusion (LPBF), Electron Beam Melting (EBM), and Direct Energy Deposition (DED)

2. Plasma Atomization (PA)

Process:

• NiTi50 wire is fed into a high-energy plasma arc, melting it into fine droplets that form highly spherical powder particles.

Advantages:
✔ Perfect spherical shape, ensuring superior flowability
✔ Ultra-high purity, making it ideal for medical implants & aerospace components
✔ Minimal satellite particles, leading to superior print quality

Disadvantages:
✖ Higher production costs
✖ Limited scalability for large-scale production

Best for: Biomedical applications, high-performance 3D printing, and aerospace components

3. Mechanical Milling (MM)

Process:

• NiTi50 alloy ingots are mechanically milled into fine powder under controlled conditions.

Advantages:
✔ Lower production cost compared to gas-atomized and plasma-atomized powder
✔ Higher surface area, improving sintering behavior

Disadvantages:
✖ Poor flowability, making it unsuitable for powder bed fusion processes
✖ Higher oxygen content, requiring additional post-processing

Best for: Metal Injection Molding (MIM) and Powder Metallurgy

Cost Analysis in 2025

The price of NiTi50 powder depends significantly on its production method, particle morphology, purity level, and application-specific requirements.

Factors Affecting Cost

1. Production Method – Plasma-atomized powders are the most expensive, while mechanically milled powders are more affordable.
2. Particle Shape – Spherical powders (for AM) are more expensive than irregular powders.
3. Purity Level – Higher purity = Higher cost.
4. Market Demand – Increased demand from medical, aerospace, and robotics industries influences pricing.
