Spherical Moulding Alloy Powder & Aluminum Alloy Powder for 3D Printing

1. Introduction

Spherical moulding alloy powders and aluminum alloy powders are widely used in 3D printing (additive manufacturing), metal injection molding (MIM), and casting due to their excellent flowability, high packing density, and superior mechanical properties.

This guide covers:
✅ Key alloy types (AlSi10Mg, AlSi7Mg, custom blends)
✅ Powder production methods (gas atomization, plasma)
✅ 3D printing processes (SLM, DED, binder jetting)
✅ Applications (aerospace, automotive, tooling)

2. Spherical Aluminum Alloy Powders for 3D Printing
