HR-2 additive manufacturing powder

The National Aeronautics and Space Administration Shared Services Center has issued a sole source Special Notice for the procurement of HR-2 additive manufacturing powder. This is a specialized requirement for 500 pounds of Linde HR-2-AM Alloy Powder with precise metallurgical specifications, including specific elemental composition requirements and particle size distribution parameters. The powder must be primarily spherical with smooth surfaces and meet strict ASTM standards for additive manufacturing applications. The procurement is being conducted under NAICS code 325199 for Basic Organic Chemical Manufacturing and PSC code 6850 for Miscellaneous Chemical Specialties. Responses to this sole source notification are due by June 13, 2025, with delivery required within 12 weeks of award.

The purpose of this procurement is to support NASA's ongoing research involving metallurgical testing, tensile analysis, and fatigue studies for potential future moon and Mars missions. The sole source justification is based on NASA's established research foundation with Linde HR-2 powder, which has well-characterized morphology and size distribution properties critical for powder bed fusion processes. Only Linde is being considered as the vendor due to the unique characteristics of their HR-2 powder and the risk that alternative materials could compromise research data reliability in NASA's EM42 laboratory. The procurement represents a continuation of specialized materials research where consistency with previously tested parameters is essential for mission-critical applications. Contractors interested in this opportunity must be capable of meeting the exacting technical specifications and delivery timeline outlined in the scope of work.
