High-Performance Spherical Powders for Additive Manufacturing

3D printing spherical powder, also known as Spherical Powders for Additive Manufacturing (SPM), refers to high-flowability, high-purity metal or alloy powders with excellent densification properties.

Thanks to their spherical shape, these powders spread evenly, melt consistently, and form high-quality parts during printing. They are essential materials for realizing precision and high-performance 3D-printed components.

Commonly Used 3D Printing Spherical Powder Materials

1. Pure Metal Powders: Titanium (Ti), Aluminum (Al), Copper (Cu), Tungsten (W), Nickel (Ni)
→ Ideal for applications requiring high purity or custom alloying.

2. High-Temperature Alloys: Inconel 718, Inconel 625, CoCrMo
→ Used in aerospace, energy, and high-heat environments.

3. Titanium & Titanium Alloys: Ti6Al4V (Grade 5), Ti64ELI (Grade 23)

4. Aluminum Alloys: AlSi10Mg, AlSi9Cu3
→ Lightweight and high-strength, suitable for structural and aerospace parts.

5. Copper & Copper Alloys: Pure Copper, CuCrZr
→ Excellent thermal and electrical conductivity, used for heat sinks and electrodes.

6. Specialty Metals & Custom Alloys: Tungsten, Molybdenum, Tantalum, Niobium
→ For extreme environments involving high temperature, density, and corrosion resistance.

Key Performance Requirements
