Metal Powders

Metal powders are essential feedstock materials used in laser cladding, laser metal deposition (LMD/DED), additive manufacturing (3D printing), thermal spraying, and surface engineering. Greenstone offers a wide range of high-purity metal powders with stable flowability, excellent spheroidization, and consistent particle-size distribution to ensure reliable melting behavior and high-quality coating or additive manufacturing outcomes.

Key Kenmerken of Greenstone Metal Powders

✔ High Purity and Excellent Sphericity

Our powders are produced using advanced gas atomization or plasma atomization technology, providing high purity, low oxygen content, and superior sphericity for stable powder feeding and uniform melt-pool formation.

✔ Wide Particle Size Range

Available in multiple particle-size distributions (e.g., 15–45 μm, 45–105 μm, 50–150 μm), suitable for laser cladding, DED, and various AM processes.

✔ Stable Flowability and Consistency

Optimized surface morphology and particle uniformity ensure highly stable powder flow for both coaxial and off-axis powder-feeding systems.

✔ Excellent Metallurgical Bonding

Powders deliver high-density coatings and additive parts with strong metallurgical bonds, enhanced wear resistance, corrosion resistance, and mechanical performance.

✔ Compatibility with Multiple Systems

Compatible with all mainstream laser cladding heads, powder feeders, and DED/AM equipment.
