Sandvik Osprey A6 Tool Steel Powder Product Information -:- For detailed product information, please contact sales. -: # **Sandvik Osprey™ A6 Tool Steel Powder | Premium Gas-Atomized Tool Steel Powder for Additive Manufacturing** ## **Overview** Sandvik Osprey™ A6 is a high-performance, gas-atomized tool steel powder specifically engineered for additive manufacturing (AM) processes, particularly Laser Powder Bed Fusion (L-PBF) and Direct Energy Deposition (DED). This proprietary powder composition builds upon the legacy of the established AISI A6 air-hardening, medium-alloy cold work tool steel, but has been meticulously optimized for the unique thermal dynamics and solidification characteristics of AM processes. Through Sandvik's advanced gas atomization technology, Osprey™ A6 delivers exceptional powder characteristics—**high sphericity, controlled particle size distribution, minimal satellite particles, and low oxygen content**—enabling the production of complex, high-density tooling components with superior mechanical properties directly from digital designs. ## **Key Features:** - **AM-Optimized Chemistry:** Modified from standard A6 to enhance processability in AM while retaining desirable tool steel properties - **Exceptional Powder Quality:** High sphericity (>95%), controlled particle size distribution, minimal satellites - **Excellent Flowability:** Designed for reliable, consistent powder spreading in L-PBF systems - **Low Oxygen Content:** Typically <100 ppm, minimizing oxide formation during processing - **High Recyclability:** Maintains consistent properties over multiple reuse cycles - **Minimal Internal Stresses:** Reduced tendency for cracking during AM build process - **Excellent As-Built Surface Finish:** Optimized for minimal post-processing - **Comprehensive Traceability:** Full batch documentation and quality certification - **Broad Process Compatibility:** Optimized for L-PBF (SLM, DMLS) and compatible with DED processes --- ## **Material Specifications: Osprey™ A6** ### **1.
