How to Choose the Right 18Ni300 Powder

Välja den idealiska 18Ni300 powder requires considering factors like particle size distribution, powder morphology, atomization process, and application requirements.

1. Particle Size Distribution (PSD)

• Fine powders (15-45µm) → Best for Laserpulverbäddfusion (LPBF)
• Medium powders (45-105µm) → Suitable for EBM & Binder Jetting
• Coarse powders (50-150µm) → Used in Deposition med direkt energi (DED)

2. Powder Morphology

• Sfäriskt pulver → Best for 3D-utskrifter due to superior flowability
• Irregular Powder → Suitable for Binder Jetting & Sintering

3. Atomization Process

• Gas-Atomized Powder → High purity, excellent flowability, best for 3D-utskrifter
• Water-Atomized Powder → More affordable, irregular shape, best for sintering & MIM
